This is the recipie I use when I need a gallon of really good bubble solution. It takes about 1 day to age, so if you need bubbles right away, just pour some detergent into some tap water. If you want really good bubbles, take the time to mix up this stuff.
Making circuits with Play-doh is pretty cool. If you have some doh at home you can use that for conductive circuits. To take it to the next level you will need some insulating doh as well. Below are recipes for both at home conductive and insulating “Play-doh”.
(You really want to use Distilled water to keep the amount of conductive ions to a minimum. Otherwise, the doh will be conductive rather than insulating.)
