What is Card Throwing?
And you probably thought this was a joke ... believe it or not ... for some ... this is an art form. I really meant this to be a tongue in cheek thing but once I started looking for references to the subject I realized that for some this is really a pretty serious endevour.
Card Throwing ... or Card Scaling is really just as it says. Holding the card in a special grip (which there are many techniques for) ... the thrower releases the card at a certain point in the throw which ideally causes the card to fly fast and straight toward it's target. Hard to believe but this is what makes our little colony we call earth so interesting.
The contemporary Western flavor of card throwing has it's roots in traditonal stage magic of the late 19th and 20th century. In addition, there is also an Eastern history that is connected to the Martial Arts. The Western flavors are believed to be originally developed and passed down from this early 19th century era of stage magic. Alexander Herrman is known to have used card throwing as part of his professional act. Thurston was another well known early magician known for his card thowing ... and one of the few known handling methods is named after him.
The Eastern disciplines of Matial Arts have been utlizing the throwing of objects as weapons for centuries. Typically the use of stars, knives, or any other sharp object would be used. The Ninja, Shoalin, and other eastern fighting disciplines perfected these arts to deadly potentials.
Methods & Technique
There are more than one technique/method to throwing cards. Many of the sites below have tutorials on the handling of the card for effective throwing for both accuracy and distance. I'm going to leave the details concerning technique to others who have a greater mastery than I. The future may allow for a more verbose coverage of technique on this page.
