Good nondestructive pranks?

[Soccerman06]

I volunteer at a camp a few weeks over the summer and we have prank wars with the counselors and cleaning crew. So all my pranks have ran their course and am looking for new good ones. Non permanent and non destructive. For both guys and girls. What do yall think. KEEP IT CLEAN its a kids/family camp? Google ones just repeat themselves

Keep it kind of cheap

Short list Ive pulled:
Soap chalk all the windows of the housing
Turned off the cold water in the shower house mid use
Fish line the doors together when everyones sleeping
Duct tape a wall over a door
Girls got some dude a bunch of tampons and pads and taped around his room (he didnt know the difference)
Saran wrapped a person to his bed while he was sleeping
Drawn on someone who was snoring in the main room with eye liner
and a few more I forget

How about a list of pranks you keep in your repertoire, so people don't suggest pranks you've already pulled?

Go the the washroom, pull out the roll of TP and glue the roll so that all the paper is stuck together. Leave 1 square dangling from the dispenser so it looks like there's a full, functional roll. Works best with those big plastic dispensers.

Hilarity will ensue.

Go to hardware store and get some long, heavy duty cable ties

Put cable tie around the drive shaft of victims car or truck.

When the person starts driving, they will hear a tap, tap, tap, tap, as the cable tie slaps on the floorboard.
