Card Trick
Found this in Futility Closet:
Take … a common visiting-card, and bend down the two ends, and place it on a smooth table, as represented in the annexed diagram, and then ask any one to blow it over.
This seems easy enough; yet it is next door to an impossibility. Still, it is to be done by blowing sharply and not too hard on the table, about an inch from the card.
(taken from Frank Bellew, The Art of Amusing, 1866)
