• A metal ring placed around the core of a vertical transformer is propelled skyward when the transformer is energized.
  • The height reached can vary from zero, to a few centimeters (levitation), to several feet by changing the transformer voltage or the type and temperature of the ring.
  • Liquid nitrogen (optional) can be used to change the temperature of a ring.





         (optimal core height ~23 cm)
         (lay transformer down for transport)
