Can you solve the 3 light bulbs puzzle? This problem requires no math or previous knowledge of the situation, just creative and logical thinking. There are three light bulbs in a room. Each has a plug that will turn the bulb on, and there is one outlet. The plugs and outlet are outside the room, and you cannot see the bulbs without entering the room. By only entering the room once, is it possible to match the plugs to their corresponding light bulbs?
