I wanted to make my own bubble solution to try and get the strongest possible bubble. It’s possible you can get the same results using store bought bubble solution.
Dawn Dish Detergent 5 tablespoons
Glycerin (95%) 4 tablespoons
Distilled Water 1 cup
Stir it really good but try not to stir up any bubbles.
I used 100% cotton for the cloth strip.
Be sure to wear gloves when handling the dry ice.
It was definitely easier to make a bubble across the smaller bowl. If you try to make a bubble across a large bowl, you may have to try many times until you get lots of the bubble solution coating the edges.
In the smaller plastic bowl I used about 2 or 3 pounds of dry ice and filled it with hot water. When you first drop in your dry ice and water, the bubble will form and pop quickly. It also releases the best looking “smoke” After about the 5th bubble, they start taking longer to form but will produce some interesting looking effects.
In the large black tub, I used 10 pounds of dry ice and enough hot water to cover the ice.
