Take a look at this cooperative learning activity. The goal of the activity is to transport nuclear waste (a cup of water) from point A to point B without spilling the toxic waste. There are several ideas given here for things to use to transport the nuclear waste: a parachute, a platform with strings or rope attached, or a can supported by a bicycle tube. As the activity requires many team members to carry the waste, there will need to be lots of communication and cooperation to successfully complete transport.
