A card is selected by a spectator.
He is asked to remember it and to repeat it mentally.
Meanwhile, the magician shows a clean slate on both sides and has the viewer sign it with a chalk.
The viewer holds the slate and chalk in his hands.
Suddenly an invisible elf climbs onto the spectator's body and slips under the slate.
When the slate is turned by the spectator himself, the card chosen and designed by the spectator will be written in chalk !!
The slate is immediately examinable
