It was around mid-January 2022 that I first noticed something strange.
I was mixing the tara gum solution as usual, and as soon as I added the detergent (Cucute Muscat scent), the liquid instantly turned cloudy white. It was as white as milk, and the part of the whisk that was immersed in the solution was completely invisible.
I was surprised, but tried the solution. Obviously, the bubble was over-moist and dripped like never before. As soon as the bubble left the wand, it could not defy gravity and fell straight to the ground.
I searched for the cause of the anomaly (cloudiness and poor performance). I suspected the involvement of glycerin (or the correlation between tara gum and glycerin), since I was experimenting with slurrying tara gum w…
・Detergent (Cucute) 354g
・Glycerin 30g (used to make a slurry from the mixed powder of PEO and HPMC)
・Citric acid 0.2g
・A pinch of baking soda
The original of this is a recipe called "Jumbo Juice" published by Dustin Skye, a well-known bubbler. This is what I applied Cucute to this recipe. With this amount, the bubbles are very easy to split. In a favorable environment, it features a very high probability of triple bubbles with breath. For huge bubbles, you may want to reduce the polymer a bit.
・Detergent (Cucute) 380g
The above amounts seem to me to be more suitable for triple bubbles.
I have recently been intrigued by the properties of commercial bubble solutions. In Japan, the bubble solutions (and toys) sold by Tomoda Shokai are known for their excellent performance.
I have not tried bubble solutions sold in the U.S. or Europe (like Uncle Bubbles), but I know that they have performance suitable for professional use and at least Uncle Bubbles are not viscous.
In contrast, Tomoda Shokai's Bubble Solution is viscous enough to be recognized at a glance.
There is no stringiness, but compared to other solutions (such as PEO or guar gum), it tangles very strongly in the wand and has a sticky feel.
However, this is not limited to Tomoda Shokai, but is common to products from all toy manufacturers in Japan. The bubble solutions av…
I use wands with three garlands between a pair of fishing rods (I call them "Triple garlands" for convenience).
The countless bubbles it blows are popular with both adults and children, and are very photogenic.
I use plastic chains to make three garlands. (Plastic chains are a material often used by Japanese bubblers.)
The biggest advantage of plastic chains is that they are "lightweight". Due to its light weight, I can use a combination of 3 (or more) garlands. (The combination of water-absorbed cotton garlands will break the fishing rods or my arms with their relentless weight.)
Previously, I used garlands made of plastic chains for both the top and bottom strings.
Some time later, I replaced the top string with a mop yarn with the aim of inc…
I was looking for a moat for KIB (Kid-in-a-bubble) that was easy to set up and solid, but I couldn't find a Japanese vendor.
There are only a few professional bubble artists in Japan, so there are no Japanese vendors selling tools for professional bubble art.
I was at a loss when I learned that importing it from Europe would be very expensive just for shipping.
I found out how to DIY on the wiki, but it's quite difficult for me ...
One day, I heard that there is a bubbler who makes a moat using a garden table (patio table).
I went to a nearby home improvement store and found a suitable product.
The table I got is made of polypropylene. It's made in Italy and costs about $ 50.
The diameter of the top plate is about 91 cm.
In my previous post (Quick test with fenugreek gum (2)), an anonymous bubbler left a comment about Tara gum.
I thought I should see if it had the same effect as fenugreek gum, so I got Tara gum on ebay.
I made a solution according to the recipe below:
・ Warm water 3,800 ml (40°C is enough)
・ Tara gum 12.3 grams
・ Dishwashing detergent (Cucute) 207 grams
・ Baking soda 2.5 grams
・ Citric acid 0.1 grams
・ Dry alcohol
Tara gum was mixed by the slurry method using dry alcohol.
The ph was adjusted to 7.5.
7:00 am, temperature 24 °C, humidity 88%, wind speed 2-3 m/s.
Unfortunately the wind was unstable and not ideal, but it seemed to work well.
May be I can reduce Tara gum a little more.
I want to see how it works under favorable conditions.
Just a quick note about making sure you let your PAM (polyacrylamide) fully hydrate and become uniform before combining with other ingredients. I was mixing up some juice (actually trying to come up with a concentrate recipe with the minimum amount of water necessary) and thought I had it nailed -- but after I used the juice, I noticed some bits of gel on the ground. It was very similar to the gel chunks you get from mixing insoluble PAM and water. (NOTE: if this happens there is a solution to the problem as mentioned at the end.)
I realize now that I had done a quick mix (using hot water to mix up the solution) and stopped my off-and-on stirring after about 20 minutes at which time I added the detergent.
Clearly the PAM hadn't really finish…
Sugiyama brothers, the most famous bubble artists in Japan, publish various videos on youtube. They also uploaded their stage show performances and I was curious to see them.
Some of the techniques they showed were something I had never seen. Among them, the so-called bubble-in-bubble (“Double”) caught my eye. They make a Double with just a single swing of the wand, without blowing into a bubble. It looked magical to me.
Immediately after watching this video, I tried Sugiyama Double several times, but I couldn't. I tried again the next day, but I couldn't. After all, it seems that the wind was the cause of the failure. I was trying this outdoors in the wind. Even a slight breeze often interferes wit…
I enjoy the bubble itself, but I'm also very interested in the process by which it is created.
I wonder and enjoy the similar bubbles that are created in a completely different way.
I've tried some minor materials so far. Some worked and some didn't.
・ Konjac: Great!
・ Fenugreek gum: Great!
・ Sodium polyglutamic acid: A sticky ingredient of natto. I could make a bubble of about 1 meter, but the film was brittle. This may be useful if you adjust the amount, but it is expensive ($ 20 for 10 grams) and not cost effective.
・ Sodium alginate (low viscosity): I probably bought one with a low molecular weight. No effect.
・ Carbomer: No effect. No viscosity.
・ Acacia Dietary Fiber: This is probably gum arabic with no visco…
I tested fenugreek gum again.
The last time was probably an overdose. This time I adjusted the amount of fenugreek gum and detergent.
・ Fenugreek gum 12.5g
・ Water 3,500ml
・ Detergent (Cucute) 190 grams
The ph was stable at 7.3, so I haven't adjusted it.
18 ° C / humidity 94%.
I was able to stably create a bubble with a size larger than the previous time. You may want to reduce the amount of fenugreek a little more.
By adjusting the amount of fenugreek, the problematic odor was improved. However, it still has a unique spicy odor.
You should avoid blowing bubbles on someone's clothes or hair.
I'm surprised that there was still such an unknown natural polymer ... Bubble is really deep.
[Added in June 2021] When I used Dawn instead of Cucute, the odor …
The other day, I found an article online about fenugreek being used as a thickener.
Fenugreek endosperm is mainly composed of galactomannan and is said to have excellent solubility and dispersibility compared to guar gum and locust bean gum. (The ratio of galactose to mannose in fenugreek gum is 1: 1, whereas that in guar gum is 1: 2 and that in locust bean gum is 1: 4. Decreased proportion of galactose makes it less soluble in water.)
A Japanese company extracted only the endosperm part from fenugreek seeds and sold it as a powder.
I was intrigued by this, so I got it online shopping, and tried it as a polymer for bubbles.
I tried it with the following recipe.
・ Fenugreek gum 17.7g
・ Water 3,500ml
・ Detergent (Cucute) 220 grams
(When I finished m…
In 2018, a Japanese bubbler released a Youtube video of a long bubble tube. The tube was long enough to extend beyond the angle of view of the camera (about 40 meters by eye) and shocked many Japanese bubblers. I am also one of them.
This bubbler published the recipe on remarks column. I contacted him. However, the ingredients of the dishwashing detergent used in the recipe at that time have been changed, and this recipe seems to be impossible to reproduce.
After that, I reviewed this video frequently and tried to learn something.
The shape and texture of the bubble tube is very distinctive. Especially in this video, the feature is clearly shown.
Somehow I wa…
I have tried several tests on konjac solutions.
There are two reasons why I was interested in konjac. The first reason is that there was a talk in the forum that konjac might produce a solution that is resistant to low humidity. Another reason is that konjac is a very familiar food (ingredient) for Japanese people.
The solution was mixed with the following recipe:
・ Konjac powder 3.3g
・ Boiled Hot water 1,000g
・ Baking soda 5.4g
・ Cucute (Japanese detergent) 262g
・ Tap water 3,834g
・ Citric acid 1.2g
1. Sprinkle konjac powder little by little into 1,000 g of boiled water while quickly mixing. (It is convenient to use stirrer.)
2. Sprinkle baking soda in the same way.
3. Stir for 1 minute every 4 minutes. Continue this for 40 minutes. (If you have a…
A Japanese commercial bubble company (Tomoda Syokai .Ltd) has created a wand for "Triple Bubble".
The other day, I tried to duplicate it. I collected materials at the "One Dollar Store" in Japan, and the total cost is about $ 4. I used small scoop nets (which for cleaning fish tank) as a material .
Made it instantly, it’s a rough construction...Well, it's just for fun.
Only successful examples are shown in the video, but in fact, the success rate is about 5%!
Perhaps that's because the sizes of the three rings are so different. The appropriate wind pressure to be applied is different for each. Therefore, it is rare that three rings form a bubble at the same time.
Improvements will be needed to increase the success rate.
(However, sometimes it su…
I tested the combination of HEC and sodium polyacrylate. It was a simple test to see what happens when I mix the two (disastrous or okay).
Temperature 4.6 ℃, humidity 82%, early morning
The solution was made with the following recipe. (The amount is somewhat arbitrary)
・ 0.7g Sodium Polyacrylate
・ 5.3g HEC (Natrosol 250HHR)
・ 1,000ml hot water (Boiled)
・ 3,334ml tap water
・ 8.0g baking soda
・ 1.3g citric acid
・ 240g Cucute (Japanese detergent)
I added mixed powder of HEC and sodium polyacrylate to hot water 1,000ml little by little while stirring with a magnetic stirrer (and after that, I added baking soda). After stirring with a magnetic stirrer for about an hour, I saw some lumps (It was clearly due to sodium polyacrylate). I added tap wa…
I tested the combination of sodium polyacrylate and Dawn Ultra.
Temperature 15 ℃, humidity 88%, after rainfall
(The bubble color profile may be hard to see because the camera exposure adjustment failed.)
The solution was made with the following recipe.
・ 3.0g Sodium Polyacrylate
・ 6,500ml tap water
・ 1.8g citric acid
・ 240g Dawn Ultra
The mixing method is described below: Japanese Soap Bubble (Dec.2020)
As far as I can see, no problem. However, there are some stringing that was not seen in the case of Cucut. For Dawn Ultra, you may need to adjust the amount of polymer or detergent.
When I was trying this solution in a corner of the park, kids rushed in and looked at it with interest.
And after seeing big bubbles and cheering, they said, "I want t…
Hi all, I am in the market for bubble solution for my children. After doing some research, I found this quite famous bubble solution that has won quite a few awards for being "super child safe". However I do find it suspicious that they do not show or state their formula. Does anyone know what compounds do they use? To be sure that it is chlid safe? thanks!
¿Existe alguna fórmula para "burbujas resistentes" que reboten o para la realización de esculturas?
No pude encontrar lo mencionado en la página.
If I wanted to store Bubble solution in an empty liquid Tide bottle would I have to rinse the bejeezus out of it first? I know it should be rinsed but just how thorough do I have to be... Is anything in Tide an enemy to bubbles?
does anyone know a bubble recipet using gaur gum that the soap doesnt kill the lawn so any detergent that i can use that wont kill the lawn
I made solutions of Guar, PEO, and PAM in distilled water and then recorded the apparent viscosity over time for 40 days, to get an idea of how quickly the solutions degrade. For each polymer I made one solution with 0.02% Propyl Paraben and one without. Propyl paraben is used as a food preservative and considered effective against bacteria, yeasts, and fungi, over the pH range of these solutions. I speculated that it could prolong the effective life of the polymer mixes.
The Guar was at 6 g/L, the PEO (WSR-301) at 4 g/L, and the PAM at 1 g/L. The Guar and PEO were slurried using 10mL of denatured alcohol per gram of polymer, and all the solutions were mixed using a relatively low shear rate paint mixer. Apparent viscosity was measured as t…
Elsewhere on this site Edward has wondered how much PAM solutions age with time so I’ve made a first attempt at measuring it. I prepared a 500 ml sample of PAM at .5 g/L with 0.01% propyl paraben (preservative) and stored it, covered, at room temperature. I then measured its apparent viscosity with a Ford #2 viscosity cup at intervals over a period of 70+ days. I did 4 repeats each time.
It takes several hours for the PAM to dissolve fully. The first measurement was 1 hour after the PAM was mixed into the water. There does appear to be some degradation after about a week.
You cannot dip the cup into PAM solution or pour PAM into the cup because it is self siphoning, so I filled the cup using a 60ml syringe. There is a possibility that there …
I experienced a "gotcha" when trying to mix up my first batch of Vincent Amendola's PVA/Guar/JLube Juice
When I added the PVA solution to the guar gum slurry, a discrete gel ball (about 5 ml big) formed in the slurry after a minute or two.
I tried to mash it up with two forks, but that didn't work. It wouldn't break up and it wouldn't dissolve with stirring. I waited 10 minutes to see if it might dissolve or soften on its own. It didn't! After about 10 minutes, I decided to try something else. I warmed the slurry VERY briefly in the microwave (20 seconds on partial power) and stirred it for a minute. It seemed to get smaller. I repeated the warm and stir process a few times, and the ball mostly dissolved, but there were still a few bits of d…
In preparation for exploring Vincent Amendola's PVA/Guar Gum/J-Lube recipe , I mixed up a 10% PVA Solution using Polyvinyl Alcohol powder purchased in 2011 or so. I know nothing about the particular type of polyvinyl alcohol that this is. The chemistry supply store had no information to offer at the time of purchase. I've made 1% and 2% solutions in the past by simply sprinkling PVA powder into water that I was stirring by hand and then warm slightly and stirring some more.
- 90 grams distilled water
- 10 grams polyvinyl alchohol powder
I sprinkled the PVA powder into room temperature distilled water while stirring by hand. When I was done sprinkling the powder, the solution was milky/chalky. I put the beaker in the microwave for 20 s…
I haven't had a chance to bubble since the September PAM Trial. I've been curious: how much PAM is too much. So, I mixed up a batch of bubble juice with roughly 200 grams of 0.1% PAM Solution per liter of juice (at 20:1 water to Dawn Pro). The juice worked quite well and was clearly not overdosed.
I had some BLM-based juice (at 20:1) on-hand and tried it. The two seemed to work fairly comparably. The BLM juice might have been able to more reliably make 40+ foot tubes BUT there weren't really enough trials to tell and the windspeed was variable enough that the difference could quite easily have been due to the wind.
Conditions: 60 degrees F, 85% relative humidity, fully overcast.
Test loops: 48-inch Rubbermaid webfoot microfiber mop top-string…
RogerH3 recently posted about promising results with Polyacrylamide (PAM) as a bubble juice polymer. Roger was kind enough to send me a sample of the PAM that he used as I was unable to find water soluble PAM myself.
QUICK TAKE: Water-soluble PAM works great. In this quick shootout it compared favorably to BLM . The test was too superficial to draw any conclusions other than PAM is a promising polymer.
CONDITIONS: 8 am, sunny, mild breeze,58F and 80% humidity
WICKS: 48-inch RubberMaid webfoot microfiber top with 2-strand white rayon bottom (from RubberMaid Rayon Finish Mop)
JUICE SUMMARY: Three different 20:1 bubble juice mixes were used (that is (20 parts water to 1 part Dawn Pro). These mixes are pH-adjusted with citric acid to a pH of 7.6. …
I've recently started playing with PAM as a bubble polymer. It looks promising but needs more investigation.
The PAM (Polyacrylamide) family is an important group of industrial polymers with an international trade value of several billion dollars annually. They come in 4 main varieties: Nonionic, Cationic, Anionic, and Cross-linked. I'm ignoring the Nonionic and Cationic varieties for now because I've yet to find a vendor with a minimum order less than 1 ton! The anionic variety I'm familiar with because the use of this in water treatment was the subject of my Ph.D. thesis, but it is not readily available for domestic use. This leaves the cross linked variety which is both readily available and cheap.
Cross linked PAM can absorb large volume…
A few years back I bought two ounces of D&C yellow #8 dye- it was one of those things where buying a little was cheap, but buying a lot was still cheap, so I bought what seems to be a lifetime supply of it. It's the concetrated form of the dye they use in yellow highlighters. It's blacklight reactive and a lot of fun to play with. I've used it to make the bath tub glow (super fun- 1/8 tsp does the trick), I've used it in play dough and I thought I'd give it a try in bubbles.
It worked/didn't work. D&C yellow 8 is a soap dye- it works well in bubbles without killing them, but even with juice that looked atomic the bubble walls were too thin to get much of an effect. Edward helped me with a thicker walled formula, but it didn't make any…
Methylated Spirit ('Meths') and Denatured Alcohol are generally considered to be alternative names used in different countries for the same thing ( https://en.wikipedia.org/wiki/Denatured_alcohol ). However there may be differences that affect their use for our purposes. In the USA I use Denatured Alcohol exclusively for slurrying Guar and PEO. When visiting England I tried using Meths, which worked just fine for Guar but not for PEO. When I tried to slurry PEO (WSR 301) with Meths I got a thick goo so I think it's partly soluble.
Bubbles are a great way to keep a crowd of kids entertained in the summer. Bubble juice is easy, and budget friendly to make, but supplying enough wands can be challenging, and expensive. With just a few basic craft supplies kids can make their own wands, and play all day!
- Pipe cleaners- available from just about any craft or dollar store.
- Yarn- Red Heart Super Saver available in pretty much any Walmart, or the recesses of most craft closets, or "I Love This Cotton" from Hobby Lobby work well. Lion Brand Homespun makes a serviceable tri-string. Dish cloth yarn like Peaches & Cream, or Sugar & Cream isn't recommended- it doesn't wick well. Chenielle/blanket yarn wasn't great either. I'm currently testing other yarns. If you hav…
When using the same bubble mix over a number of days I have often noticed a change in the pH from one day to the next, and I've seen similar comments elsewhere on the wiki, so I thought it would be worth studying in more detail. I made fresh mixes of 4 different types of mix and then recorded the pH over 10 days. pH v. time is shown on the graphs.
2 100ml samples of each mix were prepared in 5.5 oz plastic portion pots and pH was recorded while stirring as the mix was prepared, after 12 hours, and then daily up to 10 days. The graphs show the pH for each of the 2 samples of each mix.
I looked at 4 different types of mix:
1) No pH adjustment.
I thought that pH changes were probably due to carbon dioxide (CO2) dissolving in the mix, so one pair…
Improved version per Edward’s suggestions Here are 6 videos of Dawn Pro bubbles changing colour as they are inflated. For each video all 7 bubbles are the same mix. The purpose is to identify the bubble size which is most representative of in vivo bubbles made with a tri-string loop. The position indicator on the right gives a measure of the bubble volumes (12 cm on the scale is equivalent to 1 litre of volume). I'm no expert on colours so I'm looking for advice.
The 6 mixes are all Dawn Pro/distilled water. pH was adjusted with HCl.
1) 40:1, pH not adjusted
2) 40:1, pH 7.6
3) 20:1, pH not adjusted
5) 20:1, pH 7.6
6) 12:1, pH not adjusted
7) 12:1, pH 7.6
I’ve let each video run until the last bubble burst, to give an idea of reproducibility. If yo…
As suggested by Edward, here is a video of Dawn Pro bubbles changing colour as they are inflated. I've made some improvements to the lighting so I hope it's satisfactory. The purpose is to identify the bubble size which is most representative of in vivo bubbles made with a tri-string loop. The position indicator on the right gives a measure of the bubble volumes. I'm no expert on colours so I'm looking for advice.
The mixes are all Dawn Pro/distilled water. pH was adjusted with HCl.
Strength/pH for each bubble:

I analysed Joy Pro for bubble longevity over a wide range of concentrations (from 3% to 12% by volume) and pH values (from about 6.4 to 9.0) with Guar at 2 g/L using the test rig I've described previously. pH was adjusted using 0.5 molar HCl in steps of approximately 0.4. The graph on the right shows the results, with the length of the bars indicating the longevities. Each test was repeated 7 times and the error bars show the standard error of the mean for each.
Air temperature and relative humidity ranged between 21C and 24C (71F and 76F) and 43% to 49%. At each pH I tested 6 mixes plus a control (12% Joy with no pH adjustment). In case the data were skewed by the variations in temperature and humidity I also calculated the relative long…
Guar mixing methods which may be just fine for everyday bubble blowing may not be uniform and may give quite a variation from one bubble to the next.
I tested six different methods of mixing guar for longevity, for maximum bubble size, and for 'success rate'. Success rate is the % of trials that actually produce a successful bubble.
I tested three types of mixer for dispersing the slurry of 2g guar/10ml denatured alcohol (aka methylated spirits), in 500ml water: an immersion blender, a milk frother, and a 2 beater kitchen mixer. For the immersion blender I tried short (few seconds) and long (30 seconds) mixing times. For the frother I tried cold and hot water.
I also tested a vortex mix in which the dry guar was sprinked directly into a vorte…
This is the continuation from my previous post where I mentioned wrapping my little tripod around my neck to shoot videos from my perspective. So, here are some pictures of the "rig" that I used and how I made it, as well as some footage of some great bubbles from my second session using this setup. Woohoo!
- 1 Setting Up The Camera Rig
- 2 Video Using The Camera Rig
- 3 Bubble Juice
- 4 Bubble Wick
I'll let the pictures tell the story of setting up the first-person bubble cam. If the story still isn't clear, please comment and ask questions so I can clarify and add more detail.
I used the rig with my old device (HTC One M7) and my current device (Moto X Play), and found that I like the video from my current device better. Although, either device fit just f…
We had some amazingly thick fog a couple weeks ago. So, I obviously had to go bubbling in the fog. More than usual, in my opinion, these bubbles look like they're moving in slow motion. A couple times, I had to look at myself in the footage (moving at normal speed) to make sure I hadn't accidentally slowed everything down. Haha!
I'm using two different wicks for these bubbles. When I'm holding the longer poles (if you can tell), I'm using a 60" top string made from a full-ply strand of Libman Jumbo Cotton Wet Mop yarn with a 120" bottom string made from a single strand of BB&B cooking twine. With the shorter poles, I attached a 48" top string of full ply Libman mop yarn, and a 96" bottom string made from two strands of the Libman mop yarn.
My first few attempts at recording my bubble sessions were definitely not failures, but I didn't really get the good footage that I was hoping for. The two main reasons were 1) my tripod was one of those short ones with bendy legs, and 2) the camera I was using was kind of old (circa 2009).
However, when I went out again to try and capture some awesome colour profiles, I came across a fun way to film my bubbles. I figured out, purely by happenstance, that the tripod legs can wrap around my neck. So, I was "wearing" the tripod. Then, I mounted the camera to the tripod and I was able to capture a bubbling session from my point of view.
So, while I wasn't able to capture the footage I initially set out to capture, I was able to replicate a bubb…
My wonderful wife was more than willing to film some evening bubbles on the street for me. Unfortunately, I forgot to adjust the white balance on the camera so the footage is all really orange. While editing, I applied some filters using Kdenlive to fix the "hyper orange" look, and it sort of worked. On the plus side, the lights reflecting off the bubbles in the evening still look cool and alien-esque. This wasn't a test or experiment of any sort, but just a good ol' time bubbling in the night. Ta-da!
On the morning of the 14th, I headed over to the school that my children attend (after school started) to make some bubbles in the wonderfully humid air (RH 92-100%). I tried to get some good colour profile shots using the side of the school...and I kind of succeeded. After using the darkness of the building as a backdrop to view the colours, I tried a whole bunch of other angles to see what I could see on video. And, while some of the bubbles looked pretty cool, they looked much more awesome in person. Looks like I need a better camera, haha!
When looking online for bubble videos, there are lots of videos that sport titles containing "...Biggest Bubbles Ever..." or "...How To Make Giant Bubbles..."
Well, this small collection of videos truly does display some of the biggest bubbles ever created. If you find a video that shows bubbles that are even larger than these ones, please let me know and I'll add them. Shazam!
Of all the amazing things I've learned from the Soap Bubble Wiki, a few of these things are not necessary at all to make giant bubbles. However, these things make the bubbling experience exponentially more consistent and/or awesome.
Here's my non-exhaustive, unordered list of simple things that have improved my bubbling experience:
- Make your bubble juice in jugs or bottles, or mix it in a bucket and pour it into a jug/bottle. I used to mix my juice in my dipping buckets (with lids). It didn't take long for the juice to get full of crud. Also, I would feel obligated to use up the entire bucket in a session...even if the conditions for making bubbles weren't that great. So now, my juice stays clean until I want to use it, and it lasts longer b…
Just a quick note documenting the simple inexpensive lighting setup that I have cobbled together for reliably capturing bubble colors for doing indoor color profile studies.
The results are excellent in terms of capturing the colors. However, I am finding that the methods that I've tried for making bubbles that I can photograph with the setup are less sensitive to differences in solutions than my standard outdoor tri-string setups. It turns out that the tri-strings I use (and maybe reasonably sized tri-strings in general) are quite sensitive to differences in 'surfactancy' or dilution than the longevity test setup or blowing bubbles and holding them on a plastic wand.
So, my search continues for finding an indoor method of making bubbles/fil…
The conditions were much better today than yesterday for comparing the detergents. Temperature was 61F and humidity 90%. Wind was slow (1-2 mph) and steady. The sky completely overcast.
The films looked similar, but the Platinum 4x films were ever so slightly thinner -- especially at the max 'stretch'. There was something unusual, however. The longest platinum tubes were not as long as the maximum Dawn Pro tubes.
Juice details. Both juices pH-adjusted to 7.6 with 5% citric acid solution. For platinum: 9 grams. For DP: 8 grams 1000 grams water 50 grams detergent 6 grams BLM
Loops: 32" top-string loops from SecureLine 3/16" cotton cord.
The platinum juice required more citric acid than the DP solution.
All in all both juices worked well. I'd give…
My info and pictures aren't nearly as awesome and detailed as
Edward's, but I figured I'd start posting anyway.
I had a great session this evening, and here's the technical info that I have:
- Temp: 15°C (59°F)
- Humidity: 89%
- Wind: 2 km/h (1.24 mph)
- Bubble Juice
- 1000 grams of water
- 2 grams of guar gum
- 2 grams of baking powder (pH adjuster)
- 50 grams of Dawn Platinum 4X (20:1 dilution)
- Wick Material
- Libman Jumbo Cotton Wet Mop
- top string: 48", full ply
- bottom string: 96", 2 strands twisted together
And here are a few photos. You can't really see the colour profile, because the shots are not taken at an ideal angle and the lighting is too bright. However, it was a lovely evening and my wife and I had plenty of fun bubbling. Ta-da!
Oh, those blurred spot…
On August 12, 2017, I performed a quick session to compare the color profiles of Dawn Pro (2017) at 20:1 and Dawn Ultra 3x at 30:1. From earlier tests, it was clear that Ultra 3x has more surfactancy than Dawn Pro, but it was unclear how much more. In my July 25 comparison, Ultra 3x at 25:1 created a film a bit thinner than Dawn Pro at 20:1. I felt that I needed to do more comparisons to find an Ultra 3x dilution that was a closer match.
Since Ultra 3x claims to be 1.5 times more powerful than Ultra 2x (which is similar to Dawn Pro), I tried 30:1. I was expecting that the film would be somewhat thicker than Dawn Pro at 20:1 -- meaning that Ultra 3x would have slightly less than 1.5 times the surfactancy of Dawn Pro.
Took a few minutes to try out Dawn Platinum 4x for the first time. I tried it and a Dawn Pro (2017) mix. Both were 20 to 1 solutions pH-adjusted to 7.6 using 6 grams of recently brewed BLM per liter of water.
The wind was swirling and fast moving. In these conditions it was hard to get a convincing read of the solutions. Both worked well. In these conditions, the color profiles were pretty similar. I'll need better conditions to get a more meaningful read.
A note about interpreting the color profiles in this session. The wind speed was constantly changing and was generally quite brisk. A few long Platinum 4X tubes ended up with thinner films than any of the Dawn Pro films. Because of the changing speed and velocity, it was hard to tell if th…
First suitably overcast morning since I made the test juices earlier this month. All juice used 1 liter of water, detergent, 5% citric acid solution for pH adjustment (to adjust to pH 7.6) and 9 grams of BLM per liter of water.
The juices were:
- Dawn Pro (2017) at 20:1. Tap water juice.
- Dawn Pro (2017) at 20:1. Distilled water.
- Dawn Ultra 3x at 20:1. Tap water
- Dawn Ultra 3x at 25:1. Tap water.
Conditions. Temperature 64F and humidity 76%. Time of day 8 am (PDT). Mild breeze.
Each solution had its own loop: 32" top-string of Secureline 3/16" diamond braid cord.
All juices worked equally well. Many tubes in the 30-40 foot range -- though the breeze was slow enough that long tubes split into individual bubbles. Several tubes would have exceeded 40 fee…
