1: Pour ammonia into a small open-top container
2: Take long stick or similar object and impale some bunched paper towels on the end.
3: Pour powdered iodine into the ammonia bucket.
4: Stir with the paper towel end of the stick.
5: Throw it away from you and cover yourself immediately. It will create a powerful explosion and will also create a very large cloud of noxious fumes. If you hold the stick too long, it will blow up in your hand. The bucket will most likely follow suit, so get away from it as well. Do not attempt to throw the bucket or you risk spilling some and therefore risk death.
6: Wholesome party sparkler!!1!
