This is a beautiful and realistic version of the magic sword optical illusion you can see here. You will swear that the metal sword passes back and forth through the upgraded ornamental sword.
One of the greatest tricks of all time because it’ll fool you even when you know how it works. The metal sword passes back and forth through any metal pin, toothpick, etc placed in the path.
Eric has upgraded the standard plastic model and made it a real showpiece. The face of the dial is from Dali’s classic Persistence of Memory depicting an iconic melting clock. The mechanism is mounted inside of a travel watch case. With upgraded sword as well.
