⭐⭐⭐

Equipment: Small cardboard boxes, various craft / recycling materials

Provide participants with small cardboard boxes and a materials such as foam, cotton balls, and newspaper. Participants choose a box and work individually or in groups to make a soundproof box, with an opening and a cavity. When they have finished, set an alarm on your phone (or an egg timer) at max volume to go off in 30 seconds, place your phone in the box, and close the lid. The groups are trying to have the quietest box.
