Have you ever seen someone show you self-tying shoelaces? It's not a great invention, but a clever bit of prestidigitation. Dave Hax shows you how this illusion is done so that you can fool other people. You'll need a bit of string, an extra shoelace, and a willingness to wear pants.
Hax is one of the best treasures of YouTube. He's filled with great household tricks and tips like this one, including how to burn a candle underwater, set up a pretty flower arrangement, and steal pizza without getting caught. Hax does not disappoint in his latest offering.
