A '''hummer card''' trick is a [[Magic (illusion)|magic]] trick involving making a [[playing card]] seem to hover. It employs a tiny thread of [[silk]]-like [[material]] that is not readily visible to the audience. The [[yarn|thread]] is attached to the center of any card by a small amount of [[wax]]. [[Magician]]s then tangle the thread around their fingers to control the movement of the card. Since the wax is not permanent, the card can be examined before and after the trick is done. Using more advanced set-ups, the card can also be made to float around the persons body or be thrown and come back.
