Mental Key Prediction by TCC & Conan Liu & Royce Luo

Effect: The magician introduces a walnut wood key pendant with a key attached to it, and begins to tell an intriguing story. Four random numbers are called by the audience, which may even be an important date or time. The magician turns the keychain over to reveal the room number inscribed on the back of the wooden keychain, which perfectly matches the four random numbers.

The keychain can be handed to the audience for examination after the performance.
