Crystal thought capacitor

A card is selected and returned to the deck. The magician displays a small Plexiglas cube, completely transparent to the audience. He shakes it, and as if by magic, the image of the selected card appears inside.

At the end, the cube can be handed over for examination and there is no trace left of the image that mysteriously appeared!

In addition to the cube with an edge length of 2 cm (0.78 inches), you will also find the gimmick, which can be personalized with an included print.
