Not a genie in a lamp, the magician has a ghost in a bottle. But he can’t wake up the ghost. He uses a pen to prod the ghost awake, but then the pen starts moving on its own. Spooky!
And the pen and the bottle can be examined by the audience, but they’ll find no trace of the ghost – or anything else for that matter. A little bit of effort goes into this one, but ths trick is completely different to everything else here in the School of Magic.
