ANTI GRAVITY ROCK TENYO T-186

You place a rock on top of frame which shows an unusual design. You surround the rock with a small enclosure, and then concentrate.The rock slowly starts to move, and eventually levitates about half an inch from the tabletop. The rock stops in mid-air. The rock doesn't move from its positions in space, even when the frame below is moved around.
Once again, genius magician Lubor Fiedler has created an incredible piece of magic. this new principle introduces a brand new method to prove that an object is floating in mid-air, with no visible means of support. There are no threads or magnets used, but you can still make an object appear to be floating. You will be able to cause many items to float, including a transparent doll, a rock and a coin.
