These bad boys are literally magical. The Stay Cool Sunglasses Trick made its big break during a magic conference in 2014 and has been a staple in the industry ever since. The gimmick allows a wicked pair of sunglasses to appear with the wave of a hand, which can then change colors at will. It comes with over an hour of instruction, and the trick’s creator teaches you all of his favorite routines. Whether you’re a magician, or just looking for help picking up girls (or guys), the Stay Cool Sunglasses are perfect for you.
