A packet trick that revolves around an expose of card marking and how cheaters always win.
You remove the four aces from a red deck while describing a special type of marking system where you could rub lipstick on the back of the cards to secretly tell what they are. In showing the cards, one of them magically turns pink.
You then describe how you can also use the ink in your blue jeans to mark the cards, and now the back of one of the cards has transformed into a blue card. Now a tactile system of marking called nail nicking is demonstrated and the third card has not only turned green but is missing a huge corner. For the finale, you prove that the last card is definitely not marked by showing it has transformed from a red bicycle backed card to one with boldly printed letters that say, “Definitely Not Marked.” You are also taught how to end clean and examinable.
Comes with all the necessary cards (some assembly required) and a link to an online video tutorial. Cards are Bicycle cards printed by the US Playing Card Co.
