This will boggle your mind -- and keep you trying to see if you can outsmart your own foot.
But you can't!
1. While seated, lift your right foot and make clockwise circles in the air with it.
2. Now, while continuing to circle, draw the number 6 in the air with your right index finger.
YOUR CIRCLING FOOT WILL CHANGE DIRECTION!

And there is nothing you can do about it.
