Supplies: Junk/supplies, duct tape, and paint.
All you need is a bunch of junk! Get a special trash bag and label "We want your junk!" Have your staff and parents collect a bunch of their old junk (empty cans, landscape piping and tubing, broken appliances, boxes, empty toilet paper tubes, etc.).
When you are going to play, divide into teams. Give each a little bit of trash and one roll of duct tape and some paint. They have five minutes to create the weirdest, most funny, artistic sculpture out of the junk. The winning team gets a prize.
