You are in a room that has three switches and a closed door. The switches control three light bulbs on the other side of the door. Once you open the door, you may never touch the switches again. How can you definitively tell which switch is connected to each of the light bulbs?

turn 1 swith on and leave it on for a good 5 mins or so, then flip the switch off and then turn on the second switch and enter the room. once ur inside, touch the bulbs that aren't on. the one that feels warm is the bulb for the first switch since it was clearly on, and the bulb thats cold is the one for the 3rd one since ye never turned it on :3
