Duct Tape Challenge (game)
Divide into even teams and have each team select a volunteer - preferably a small, light one. Give each team a roll of duct tape. The object is to tape a team member up on to the wall, using no more than the provided role of tape. The one who stays up the longest is the winner. (At one event, a middle school kid was on the wall for 30 minutes!)
Hint: Make sure you use the tape that doesn't leave sticky stuff on the wall or tear off paint (especially in rented or borrowed facilities!) Provide a soft landing for youth as they drop off the wall!
