A Cat in a Spot by Eric Hu

A Cat in a Spot is a genius way of using a Post-it pad to effortlessly make the impossible ACAAN possible.

The magician shows a spectator a Post-it pad with random numbers and cards written onto it before handing them a deck to come back to later. The spectator then picks any random page on that same pad to receive a number and then again to receive a card.

Then with the deck they have been holding the entire time, they deal down to that card at that exact number.
