The magician holds a matchbox and a long needle with a ribbon passing through the eye of the needle. He holds the matchbox with one hand and draws attention to a small hole in the center of the face of the box. He passes the needle through the hole and the ribbon is seen clearly on both sides of the matchbox. The spectator is asked to pull the ribbon out of the box and the magician asks the spectator if that was amazing. Of course the spectator didn’t find anything interesting or amazing about that. The magician seems to be disappointed but then suddenly remembers something. He says that he forgot to tell them that what he has done is an impossible phenomenon as the entire interior of the matchbox is occupied by a solid brass block. The magician pulls the matchbox drawer open and shows that indeed there is a solid brass block. The block is dropped into the spectator’s hand and it is a heavy, solid brass block without any holes in it.
