TED-Ed: Can you solve the giant iron riddle? - Alex Gendler

The video presents a scenario where a giant needs to iron a shirt for a dinner party but the batteries for the iron are mixed up. The challenge is to find a working pair of batteries in 7 tries or less. The solution involves dividing the batteries into smaller groups and testing combinations to efficiently identify working batteries. This method ensures a working pair is found quickly, allowing the giant to iron the shirt in time for the party.
