You can produce a mini Rubik's cube from a playing card, but in a very mysterious manner!
After displaying the back of a playing card, the magician shakes the card gently and the shadow of a Rubik's Cube appears on the card. After one more shake, a real mini Rubik's Cube falls into the performer's hand - from its shadow!
It's visual and very easy to do, a must have for visual magic lovers.
