Dry Ice Bomb
Materials
1. Some kind of plastice bottle, small water bottles work the best
2. Dry ice, you dont need alot just a few pieces small enough to fit in the bottle
3. 1/2 cup of water
To make the bomb its simple. Pour the water into the bottle. Then stick the dry ice into the bottle and quickly skrew on the cap. Through the bottle away from you and wait for the BANG!
KEEP IN MIND! -
The bomb is very loud and shards of plastic will fly in random directions so be careful.
