This is the magical pond puzzle: There are three temples on a magical pond. Before visiting each temple, you must swim through the pond, so your path is pond, temple 1, pond, temple 2, pond, temple 3. After each swim, the pond triples the number of flowers you're carrying. You begin with some flowers, and you place the same number of flowers at each temple. You finish with no flowers. What is the least number of flowers you could have started with? How many flowers did you place at each temple? The answer to the logic puzzle can be found by watching the video below. Then, try your hand at some other brainteasers.
