Just to throw an interesting twist on this one... if you surround the bottle in a container of some sort of powder (like a plastic bag full of flower or chalk) you get some interesting effects
. When I can find out where to get a hold of some dry ice, I'm going to put a setup like that in a suite at school (we have 3-room suites off the hallways, instead of long hallways of rooms). I figure it would be a pretty damn funny way to wake someone up. Then they open the door, and the entire suite is filled with flower.
