Try This  

Left Brain, Right Brain

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.

Your foot will change direction and there's nothing you can do about it.

Lay a dollar bill on the floor about 2 feet away from a wall.

Stand with your back to the wall.

Without bending your knees or twisting sideways and with your heels touching the wall try to pick up the dollar.
