This effect is very amazing and cool
The spectator chooses a card and signs it and then loses it in the deck,
Then the magician writes his guess on the back of the random card, but it's a wrong guess...
Then this is what happens , the magician shakes it a little bit and the ink slowly disappears and leaves a hole in the card...!!
And what's even stranger is after we look for the cards one by one, it turns out the ink teleports to the spectator's chosen card which is signed...!!
The spectator will definitely be stunned to see it...
