Hyde cube is a surprising effect with a great impact. The spectator can choose one of the 52 cards of a deck. And the cube that was previously left inside a paper bag will reveal the value and suit of the selected card, even before it is revealed.
Many routines are possible with Hydecube, for example, as you can see in the video performance, the value and suit of a chosen card, can even appear in the hands of a spectator.
You will therefore be able to create really incredible predictions and revelations!
