Let’s Begin…

Someone has tripped the magical alarms in the Element Temple. When you and the other monks arrive on the scene, you know you have a disaster on your hands. Four young apprentices broke into the temple’s inner chamber to steal the sacred element crystals. But when the alarm went off they panicked, and each of them swallowed a crystal. Can you determine who ate which crystal? Alex Gendler shows how.
