TED-ED: Everything changed when the fire crystal got stolen - Alex Gendler

A group of young apprentices accidentally swallow sacred crystals, risking transformation into elemental spirits. The monks must determine who consumed which crystal using logic and proof by contradiction. The elements compel truth or lies, adding complexity to the task. Through strategic guessing and contradiction, the monks identify the crystal holders and prevent disaster.

What disaster occurred when the young apprentice broke into the temple's inner chamber?

What must be determined about the crystals consumed by the monks?

What is the consequence for those who consumed the earth and water crystals?

How does the technique of proof by contradiction help in solving the problem?

What conclusions can be drawn about the identities of the monks based on their statements?
