A Zoomdoggle reader sent them a little challenge. If you can’t read the handwriting, it says:
While sitting at your desk, lift your right foot off the floor and make clockwise circles. Now, while doing this, draw the number “6” in the air with your right hand. You foot will change direction and there’s nothing you can do about it.
I’m a complete statistic – my foot switched directions. Give it a try and let us know how it went for you.
