This project by Rick Findley creates a compact easily portable KIB rig from two differently-sized inflatable baby pools. This design was used exclusively for KIB demonstrations during the 2015 Boston Bubble Daze IV event!

One moat

INTEX makes widely available 3-ring inflatable children's wading pools in sizes suitable for making KIB moats. They are labeled as having diameters of 45",34" or 24" diam, but the actual diameters are somewhat different.

Two moatpg

You can make a large size moat or a smaller size with a combination of the 3 sizes available (ie. another 34" bottom pool for the larger moat becomes the top piece for the smaller moat). You will need a 34" diameter hoop for the larger moat and a 25" diam. hoop for the smaller moat. I have used the smaller hoop many times for adults.

 
Three moat

Remove the top 2 rings by cutting along the top of the bottom ring just above where it is attached to the middle ring.

Fourmoat

Inflate the larger 1-ring wading pool & locate the very center of the pool and mark it (as shown).

 
Five moat

To draw a 9" radius circle for removal, attach a 9" string to a center post of some sort (a pencil or stick, etc.) and a marking pen. Use this as a compass to draw your circle. The size is somewhat arbitrary--you can cut out a circle of any workable size you want.

Six moat

Here is an 18" diameter center circle marked for cutting. Again, the size is arbitrary.

 
Seven moat

Now you have 2 inflated pieces. Once the larger piece is placed over the smaller one you have an instant moat effect.

Eightmoat

Smoothed out and tucked in with the larger piece placed over the smaller piece. The bottom piece catches the splatter from the bursting bubble tubes and may begin to puddle a bit after extended use. You can place a folded towel in the center to sop up any puddling and just continue.

Ninemoat

You can add a non-slip center bullseye made out of 120 grit emery paper using contact cement. To empty the pool and minimize foam simply scoop out the juice with any cup into a bucket. In order to deflate the pool pinch the base of the valve stem together which opens the inside valve to release the air. Caution: When using an inflatable style moat it is important to sweep and clean the area the moat will be resting on, along with a protective sheet or blanket type material underneath to minimize punctures and tears.
