Ink Permeate by Dingding

Coin thru card..like you've never seen before!

With a Sharpie, you draw a line on a selected playing card. You then borrow a coin and it magically passes through the ink line that they just saw you draw on the card! Just like a coin-slot! You then remove the ink line from the card, and the card is shown to be whole, with no slot in it at all!
