Hi! I’m Greg from Expert Village, and I’m
going to show you some easy to do magic tricks that you can perform at work. The shadow pen.
You need a round pen for this one or a straw. That works as well; it’s even better. Just
place it on the table top. Now, cast a shadow over it, and when the shadow touches the pen
blow on it. Blow on it. It will cause the pen to move. If you can, blow through your
nose. That way people can’t see you blowing. Just like so.
