- Piece of cotton cloth
- Optional: Light sticks
Heavy duty gloves
Piece of cotton cloth
(Optional: Lights sticks)
STEP 1:
Using heavy duty gloves, place dry ice in bowl that's halfway filled with warm water.

STEP 3:
Use your finger to place dish soap around the edge of the bowl (BUT BE CAREFUL NOT TO GET ANY SOAP IN THE BOWL! As this will cause lots of foaming).

STEP 4:
Take the piece of cloth out of the cup of dish soap and water and wipe any extra soap off of it, then wipe it across the edge of the bowl (see video) You might have to go over the bowl a couple of times before the bubble forms. Go slowly.

STEP 6:
Optional Step: Drop a light stick in the bowl before you add the dry ice and water.

The reaction between the water, dry ice and soap film causes a bubble to form. The soap film creates a barrier over the bowl and the dry ice can't escape until the bubble bursts. *Never touch dry ice with your bare hands. | 1. What causes the dry ice in the bowl to form a bubble? 2.Would food coloring change the color of the bubble? 3.What would happen if you used a different liquid instead of water? |
