This is so funny that it will boggle your mind.  Keep trying at least a few 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.

 

I told you so.  And, there's nothing you can do about it!

 

Go ahead KEEP TRYING ALL YOU WANT!
