This video explains the process of making a dry ice bomb. In order to do this you only need a few basic items. All you will need is a water bottle, some water and of course the dry ice. The hardest thing to find will be the dry ice. In this video they show the phone number for the place where they got their dry ice. Once you have all of the items you will need, you just take the water bottle and fill it up about one-third of the way with water. You then put the dry ice into the bottle with the water and close the cap. Then make sure to either throw it or set it down and run.
