1.   The team must design and implement a method of lowering the ring to the bottom of the winding copper tubing with the fewest touches.
 

2.   No one may enter the circle at any time.

3.   Remind teams to be honest and hold themselves accountable for touches.

4.   Try goal setting. Ask the group to set a goal for the fewest touches and try to beat it. Provide an opportunity for them to start again.

The team must complete the task in 25 minutes or less.
 

Be sure to begin with a larger ring, and then graduate your group to smaller ones (if you have the time).
