Pen spinner

The other day we had some visitors. As a thank you, we all got a nice and shiny pen.



The thing is: it's a very weird pen. It is balancing on a kind of a turn thing. If you give the pen a small tap, it will spin round like a helicopter.

[ no idea what the function is, but spin it will... ]



To be honest, the pen is no good. It just stands there on my desk. And that is in fact the beauty of this pen! You never take it with you, so it's always there on your desk.
