Things You'll Need:
- Empty 20-oz. water bottle with lid
- Scotch tape
- Paper towel
- Paintballs
- Scissors
- Baking soda
- Vinegar
-
Step 1
Take a paper towel and fold it in half. Make sure the crease and the fold are as straight as possible.
-
Step 2
Pour two tablespoons of baking soda down the middle of the paper towel in a straight line.
-
Step 3
Take your paper towel and fold it in half again, this time from the top to the bottom to make a square. Use scotch tape to secure the sides of the square packet.
-
Step 4
Remove the cap from an empty water bottle and drop 10 paintballs into the bottle. Add a cup of hot water to the bottle and shake it up. This will help the paintballs to dissolve.
-
Step 5
Pour half a cup of vinegar into the water bottle. Stuff the square paper towel packet into the bottle, cap it, and throw it in an open area outdoors. The baking soda and vinegar will mix, cause pressure to build up in the bottle and cause it to explode.
