The Circle Game

Shamelessly lifted from the NHS Blog Doctor:

This is so funny that it will boggle your mind. And you will keep trying at least 50 more times to see if you can outsmart your foot, but you can't.

1. While sitting at your desk, lift your right foot off the floor
and make clockwise circles.

2. Now, while doing this, draw the number "6" in the air with your right hand.

Your foot will change direction.

And there's nothing you can do about it!
