A new brain teaser every day at midnight UTC. Can you keep your streak?
easy
One day an alchemist brought a king a bottle holding a strange liquid. The alchemist said, "This liquid I discovered will dissolve anything it touches." How did the king know that he was lying?
If what he said was true the bottle would get dissolved
Why this works
This riddle plays on the concept of contradiction. If the liquid truly had the power to dissolve anything it touched, then it would also dissolve the bottle that contains it. Since the bottle remains intact, the king can deduce that the alchemist is lying about the liquid's properties. It's a clever way of highlighting logical reasoning by showing how the physical evidence contradicts the claim!
