• 1.My cardboard boxes with dials on them and paper disks in them. 2. The jug, bicycle pump, and thermocouple (pump air in --temperature goes up until cork pops out and then temperature plummets) 3. An empty plastic soda bottle with the cap screwed on -- an air conditioner (same concept as #2, except as a hand-prop -- I'll squeeze it "outside" and let heat flow out, then I'll go "inside" and let it expand so that heat flow in. Thanks!
