This is sort of a mild explosive, but it can be quite dangerous in large quantities. To make touch explosive (such as that found in a snap-n-pop, but more powerful), use this recipe:
– Mix iodine crystals into ammonia until the iodine crystals will not dissolve into the ammonia anymore. Pour off the excess ammonia and dry out the crystals on a baking sheet the same way as you dried the thermite (in other words, just let it sit overnight!).
– Be careful now because these crystals are now your touch explosive. Carefully wrap a bunch in paper (I mean carefully! Friction sets ’em off!) and throw them around.. pretty loud, huh?
