Dry Ice!!!!

Ok for those of you that dont know when you put dry ice in side a plastic bottle and fill with water then close the lide quickly the gas expand and expand until it explodes and is as loud as if not louder then a shotgun! Now when you set one down and get annoyed that it hasn't exploded DO NOT run up to it and kick it this is what happens to your arm if youra impatient little prick lke myself!
