A trick straight from ancient Egypt, the Mummy Mystery magic trick.
Here is how the trick works: The magician chooses a volunteer from the audience, the volunteer is then free to select any mummy of their choosing (this trick will work no matter which mummy is chosen so there is no forcing required). Next the magician then turns around, the selected mummy is placed into a sarcophagus, and the other two mummies are hidden from site by the volunteer. Finally the magician turns around and revels almost instantly which mummy was selected even though the volunteer has closed the sarcophagus and hidden the other two mummies.
