Push a card so that it penetrates right through a transparent blue crystal. Cause a coin to sink down into the crystal, and then rise back to the surface. Your spectator can immediately touch the solid surface of the crystal, there are absolutely no holes or slots anywhere.
So good it will leave you experiencing the astonishment too, when the crystal surface that you just touched allows coins and cards to sink inside. This super visual effect will cause you to question your own eyes.
Created for Tenyo Magic by Lubor Fiedler, the brilliant Austrian magician responsible for the invention of many eye deceiving and mind bending tricks.
