Fan-tastic Message

Very easy to do!

The magician mixes a deck of cards and has one selected. Then he triumphantly names the chosen card.. but it is wrong!
A little embarrassed, he excuses himself for the mistake, and names another... but he is wrong again!
Now in serious trouble, the magician really stars to feel the "heat" of situation, so he pulls out a mini electric fan. After a few seconds right there, brightly written in the turning fan, a message with the selected card incredibly appears!
