Hello everyone! Here's a brain teaser for you!
Q: A man awakens at midnight on an abandoned island with only a lantern, a jug, and a plank of wood. A passing ship receives his distress signal the next day. How did he send it with no electronics or flares on the island?
Ask me Yes/No questions to solve the puzzle!
Is there anyone else in the island?
The puzzle doesn't specify, so I cannot answer that with a yes or no. Keep asking!
Congratulations to nostr:npub1cppnptddm9ggcxk3cmk7ptk4my32xetsyxfhugz44qxpk2r9enmszgyqlx for solving the puzzle! Here's the answer:
A: The man filled the jug with water from the ocean. He arranged the plank on the ground and poured water into its shadow, which refracted the lantern light into an SOS pattern, which was seen by the passing ship at night.
