A few years ago, when my son was in high school, the vandalism of choice was to super glue your enemy's hall locker shut in just this manner.

A few years ago, when my son was in high school, the vandalism of choice was to super glue your enemy's hall locker shut in just this manner.

My favorite for lockers was to use clear caulk arounf the door edges and vents, then siphon 5 gallons of water into it from the top vent.

When I was in HS, we did a variation on the "mess with somebody's locker" prank. One time, we broke into the guy's locker, and put a carton with week-old really ripe urine in it, sealed with plastic wrap, and a string tied to the door. Very carefully close the door shut, and when the guy yanked open the door, he got a surprise. :-)
