The Magic Sword Optical Illusion is the latest version of a classic illusion where a sword amazingly penetrates a solid object. It can be repeated many times and will still fool you.
Invented by Moritz Heinrich Böninger and patented in 1932-1933. It creates an impossible illusion of a knife repeatedly penetrating through a toothpick or any such object. It is truly a mind-boggling illusion that seems impossible even after you know how it works.
