This is so hilarious and it will boggle your mind.And, you will keep trying it 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 with it.
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 is nothing you can do about it.
