Gallium Spoon Tricks

Gallium Spoon Tricks Gallium is a shiny metal with one property in particular that makes it perfect for science tricks. This element melts just above room temperature (around 30Â °C or 86Â °F), so you can melt it in the palm of your hand, between your fingers, or in a cup of hot water. A classic set-up for gallium tricks is to make or purchase a spoon made from pure gallium. The metal has about the same weight and appearance as stainless steel, plus once you melt the spoon, you can reshape the gallium to use it again and again. Gallium Spoon Materials You need either gallium and a spoon mold or else a gallium spoon. Its a bit more expensive, but if you get the mold, you can make a spoon over and over. Otherwise, youll need to mold the metal by hand to re-use it as a spoon. The Mind-Bending Gallium Spoon Trick This is a classic magician trick in which the trickster rests a gallium spoon on a finger or else rubs it between two fingers, appears to concentrate, and bends the spoon with the power of his mind. Youve got a couple of ways to pull off this trick: Rest the spoon on a finger that you warmed up right before the trick. Easy ways to warm your hand are to hold a cup of hot tea or coffee or simply put your hand under your armpit briefly.Rub a section of the spoon between two fingers. Friction generates heat, which will soften the spoon. The weight of the spoon will cause it to bend. The Disappearing Spoon Trick If you stir a warm or hot cup of liquid with a gallium spoon, the metal melts almost immediately. The spoon disappears into a cup of dark liquid or pools visibly at the bottom of a cup of clear liquid. It behaves much like mercury (a metal that is liquid at room temperature), but gallium is safe to handle. I dont recommend drinking the liquid, though. Gallium isnt particularly toxic, but its not edible.
