Spoon bending is the apparent deformation of objects, especially metal cutlery, either without physical force, or with less force than would normally seem necessary. It is a common form of stage magic, and a variety of methods are used to produce the illusion.
Spoon bending attracted considerable media attention in the 1970s when some people claimed to have the ability to cause such events by paranormal psychic means. The most notable was Uri Geller, who performed by bending metal spoons as well as metal keys and several other objects and materials. Geller's performances were attributed to stage magic by critics such as James Randi and Martin Gardner.
Causing spoons, keys, and other items to appear to bend without any physical force is a common stage magic trick that has many variants. Simply holding a spoon by its neck and rapidly tilting it back and forth can create the illusion that the spoon is bending, due to the way that the human eye perceives the rocking motion.
When a spoon is physically bent or broken, it is usually at the point where the object would be easiest to bend by hand. In many cases, the trick uses misdirection, a basic tool of the stage magician. The performer draws the audience's attention away from the spoon during the brief moment while the spoon is being physically bent. The typical bend, where the bowl meets the handle, requires relatively little force. The magician then gradually reveals the bend. When a 1996 BBC television show staged a prank on Uri Geller, it took footage from angles he was not expecting, which showed Geller grasping a spoon firmly with both hands as he stood up to display a bend in it.
Other methods use a metal spoon that has been prepared so that a simple flick will cause it to bend or break. This can be done, for instance, by repeatedly bending the spoon at the desired spot, until the metal cracks and weakens. If the spoon breaks, the magician holds together the two halves of the spoon as if it were unbroken, then slowly relaxes the grip, making the spoon appear to bend before splitting in two.
