If you want to laugh your ass off fill up a gallon milk jug with water and hit it with full power 00 buckshot at about 15 feet.
Instant vapor cloud, can't find water jug.
The first time we did this I laughed so hard. As you watch the jug (someone else shooting) it's there, then it's not. They just vanish. I think the plastic vaporizes too.
Plus you get the added benefit of cooling off on a hot summer day. Needless to say, don't do it with milk.
