The spectator chooses a card then the card is inserted into a box which has a hole on the front the size of a coin,
Then we tap the card in the box from the hole with a marker, but strangely the card can penetrate the box...!!
Which the box is intact without a tear on the back...
After that the spectator can try it by inserting the card back into the box and doing the same thing as we did but 100% failed..!!!
And the bonus is that everything can be examined by the spectator from the box, card and marker...!!!
