This game, which can unfortunately become expensive, involves creating things from random materials. I started buying materials from a local craft store and bought 4 of everything. It included styrofoam balls (large and small), dowel rods, animal fur, yarn, tape, colorful pipe cleaner, empty 2 liter coke bottles (a must), feathers, stick glue, etc. Divide up the teams and allow them to work on their creation. Guidlines are a good idea. Such as it has to be a robot, person, or animal. Give it a name and possibly a story. The crowd loved the inventions.
