Robert has baked rare earth metals into this superconducting cube. It is attached to a special plastic plate with glue that can with stand the -320 temperatures of liquid nitrogen. The "plate" is a rare earth magnet ring that levitates on top of the cube when the cold temperature of the superconductor is reached.
Any round food item can sit inside the ring as it turns and spins. It is imposiible to not sit there and stare at it in amasment. How can this be done? I have already had thoughts about eggs, bubble gum, spheres, you name it. Thanks again to Robert for helping me make my dream come true. We will be getting in more "plates" in so our guest can play with their food.
