I need help in preparing tests for quality of soap, I wrote also on FB, can you help me with this. I have some university people who help me with recipie but need help for finding how to mesure good quality soap.
Hi Edward and everyone else who have spent their time and energy to help this wonderful pastime to develop to what it is today. As a Cub Scout leader (Boy scout leader for those in the US) I came across this site last year when I was putting together theme for one of our many weekend camps. My chosen theme was giant, originally based on a wish to make a GIANT slingshot as the basis for a giant angry birds activity. The angry birds was a huge hit but paled in comparison to the lasting effects of the giant bubble activity I put together (based primarily on your, Edward, input and research). I have since run the activity about 1/2 a dozen times, each and every time it has been a huge hit.
My son's teacher was interested in the possibilty of making it into a STEM challenge for her class and a few weeks ago I did a guest spot with their class using bubbles to explore Sceince and Mathematics, they are an accelerated class of 10/11 year olds (year 6 here in Australia). I used the science and technology to explore things that included, bubble technology to explore development of surfactant medications to help premature babies survive, we talked about how bubbles can help plan roads, we explored the composition of a simple bubble wall and the effects of colour interference. After the cognitive parts we then set up an experimental design where the class all tested 6 different solutions (3 different detergent to water ratios non-PH adjusted + the same three PH adjusted down to 7.2). The pupils then decided on the 'best' mix based on criteria they setup (and recorded). As I had made large amounts of the mixtures (30 litres of bubble mix) we then gifted each student about 1/2 a litre to take home (after we adjusted it to the "best" dilution and to PH 7.2). It was a huge sucess and the discussion/experimental design has been requested for other classes. Thanks to everyone here for helping me with all of your shared knowledge!!

Thank you for your suggestion on adding or soap to make my HEC bubble lighter. It worked great. One other quick question. I noticed after about 2 weeks the formula changes to a cloudy color and the consistency changes as well. Is this just the normal way it degrades? Photo attach.
I've been challenged to create a demonstration involving a side by side bubble comparison, where bubble A will outlast(not burst) versus bubble B, which should always pop first. I need two formulas that will work every time. They don't need to be the same recipe base, but that would be ideal if possible. The bubbles don't need to be large (3-5 inch diam.) and will be blown into the surface of 2 petri dishes, using cutoff pipets for wands, inside.
I've read thru much of the site and found some great information, Kudos on a great site BTW. I have many of the basic ingredients on hand like Jlube, surgilube etc. I need your advice on which recipes I might use for this. What might I use to help improve the reliability, either making the a formula stronger, or the B formula quicker to burst.
It occurred to me that pH manipulation might do the trick, but frankly, I'm a novice and don't have a whole lot of time to learn, what you (the bubble master)likely already know. I was thinking of using one with BLM and one without. What do ya think?
Thank you for editing and placing the file(s) in appropriate places, Espiegel123. Also for the comments on the crocheted wick.
I'll endeavour to add a blog entry as soon as I can (just getting prepared for a holiday at the moment, though).
I just tried editing the title of the image to give it a more appropriate noticeable name, but failed. IF you have chance, could it be renamed to something like the description I just about managed to add? - "Crocheted cotton string wick" instead of IMAG0124.jpg?
My name is Mark, I live in Wales and have been "bubbling " for over 20 years.
I love this site for the great information. I have just put a video I made of some bubbles I did on youtube. Can I post it on here ?
Great to hear from you. I hope you won't mind that I reply in English. My French is not very fluent. If you would like to add articles here that would be great. Besides being able to post articles in the main space, every user also gets a blog space which Rick Findley , for example, has put to great use sharing his many bubble inventions and experiments. I use my blog space for my ongoing experiments before I feel that the conclusions are solid enoug to move to the main site.
