I don't know if you have ever tried or seen this, but i just heard about it today from a friend....
At your desk, lift your right foot off the ground and make clockwise circles with it. THen while doing that take your right hand and spell a the # 6 in the air, and your foot will change directions!
You might need to do it a few times to actually see it.
IF anyone knows an explanation to it, or anything tell me.
