Experiment 02: The Growing Head Illusion
The Growing Head illusion is one of the most mind-bending optical illusions ever discovered. Simply gaze at the center of the spinning spiral for 20 seconds, then look at your friend, and it will seem as though his or her head is expanding like a giant balloon. The illusion typically lasts for as long as 10 to 15 seconds. Reverse the direction of the spiral, and your friend's head will seem like it's shrinking.

The trick, if performed correctly, is a pretty interesting optical illusion. This guy clearly doesn't have the disc mounted to the drill on center.
