The magician displays a plastic pen, which is shown to be a solid, working pen.
He chats a little about the people who are able to bend spoons and keys just by mental concentration.
As he's talking, the performer rubs on the pen and it becomes flexible, bending like rubber.
The pen is rubbed once again and becomes solid, and can be handed out to the audience for total examination!
