- How to make a dry ice bomb - This is one of the most simple bombs to make. It is used for many different things. If your just out having fun take a two liter soda bottle and fill it three quarters with water. Then take a piece of dry ice and crush it. Put just enough to make a layer at the bottom of the jug. Now cap it and run! You wil have about 10 to 15 sec before it detonates. It will make quite a boom! I set of a car alarm 30 - 40 feet away with one of these! Now if you are in a war or need one for self defense you can do the same procedure exept use a glass bottle. this will throw glass shrapnel, so it can do some damage on a human. Do not in any way use this on a person unless you are AT WAR!!!! So be careful!! **CAUTION** There is no set time for detonation so it is NOT wise to hold in your hand!!!! Here are a few other things you can do with dry ice: 1. Mix 1 part egg, 1 part paint, 1 part, wipped cream, and fill a two litter bottle with it. Put about two inches of dry ice in the bottom. Cap it and get creative. ------Vortex
