You are in the basement of a house where there are are three identical on off switches. Outside of the closet there are three light switches. Go upstairs and touch the bulb. That is switch on 1 2 wait a minute switch off two and go to the attic and check if the bulb is on hot or cold.

Switch 1 leave on 5 minutes then shut off. The famous light bulb riddle. You can play with the switches as much as you want and after that you can visit the attic above just once. Inside is a single light bulb controlled by one of the three switches.
