Swiss Pack by David Acer
A card is selected and returned to the deck. The magician announces he has now marked the card in a subtle way so he can find it - when he spreads through the cards, one has loads of holes punched through it! It's the chosen card!
The magician now offers to repair the selected card, and the holes in the selection visually vanish!
Where did the holes go? They went through the whole DECK! The whole pack has a large hole running through the centre!
'It is a wonderful walk-around trick; very magical and bound to produce a good deal of laughter.' - Aldo Colombini.
