The Hummer card is a levitation magic trick in which, unlike many other levitation tricks, a regular playing card floats, hovers, spins and flies around the body of the magician in a seemingly impossible manner. The trick works for any form of card such as a credit card or business card. Due to this flexibility it is often used as street magic or a fancy way for a corporate magician to hand out his business card, and is very easy to work into almost any routine. The trick was originally invented by Bob Hummer and is often sold on mainstream magic sites.
It is often referred to as the Hummingbird card. Some dealers sell a rebranded version with a variety of different names, such as Hummer's Whirling Card.
