Introduction: Film Canister Foam
You are going to need:
Duck tape or paint to decorate
Step 1: Step 1
Take off the lid of your canister , paint the canister ,or cover it with duck tape.
Step 2: Step 2
Fill up the canister 3/4 of the way with vinegar. Then, color the vinegar blue.
Step 3: Step 3
Put about a teaspoon of baking powder into a square or toilet paper. Then, twist it up.
Step 4: Step 4
Place the toilet paper into the canister. (I had to change the toilet paper and baking powder). Quickly put the lid on and shake the canister.
Step 5: Done!!!
After you shake it you get blue foam. This is what it looks like on the outside when it is foaming ,and inside after it is finished. I recommend having some friends over and doing many at once. You can try it with larger containers and mix up the proportions of baking powder and water.
