A close-up item looking like a miniature clock, apt for mind-readers. Time is set on the clock as per the spectators choice. When the other side of the clock is displayed, it shows the same time, which is the prediction of the mind- reader!

Suddenly the hour hands vanish from both sides of the clock and mysteriously appear!

A must tool for mind-readers. https://www.murphysmagicsupplies.com/video/clips_mp4fs/
