夢想出走、夢想吾撈、夢想美食

Try this

1.  While sitting where you are at your desk in front of your computer, 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!

 And there's nothing you can do about it! (don't tell me you write the number '6' the other way round ... we are not asking how creative you are but can you "outsmart" your right foot .....)
