A windowless room has three lightbulbs. You are outside the room with 3 switches, each controlling one of the lightbulbs. If you can only enter the room one time, how can you determine which switch controls which bulb?
Solution:
Turn on switch one and two. Wait a little while and then turn off switch 2.
Go in the room to check out the bulbs:
Switch 1 corresponds to the bulb that is ON
Switch 2: Corresponds to the bulb that is OFF but HOT
Switch 3: Correspond to the bulb that is OFF and COLD
