Magic Floating Cube
At first glance, this small cube with the words “Happy Birthday To You!” written on it does not seem real. It almost looks like an animated cube added to the video in some sort of post-production process because the peculiar way that it moves.
The end of the video shows a slightly different angle revealing the true construction of the cube. It is inside-out, but your mind perceives it as being a normal three-dimensional object. It has a construction that is similar to the Dragon Illusion and Crazy Nuts Illusion originally created by magician Jerry Andrus.
