Show a vintage golden key. With your finger rotate the teeth for several steps. Then move it towards the handle of the key. The audience will clearly see the teeth slide down along the key from the tip to the handle. It all happens very slowly and without any cover. In the end, the teeth will be permanently welded to the base of the key.
