A curved jumping disk??? The sky's the limit for these disks, which have two layers of bonded metals with different thermal expansion properties. A change in temperature causes these disks to jump approximately 12 inches or higher into the air! Simple enough for elementary students; challenging enough for AP physics classes! 25 mm (1 inch) dia. Pkg. of 10.
