The Devil’s Hank is an accessory for magicians. It has been in the industry for decades due to its extremely simple and effective method for making small objects disappear, switch, or appear.
A handkerchief is clearly visible on both sides. The four corners are gathered to form an improvised pocket, and the object to be made to disappear is dropped into the pocket. The handkerchief is then opened flat, held by one corner, and the item has vanished. It is opened flat and clearly displayed on both sides, and there is no trace of the item.
