Basement attic light switch riddle. Turn on one switch for five minutes then turn it off. Outside of the closet there are three light switches. There are three switches in a basement. As long as you don t stop for a beer before running up the light that s off but warm to the touch is the first switch.

You can turn the switches on and off and leave them in any position. It s basically the same solution as our first idea.

You must determine which needs saving and remove the other two. 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. How can you figure out which light switch goes to which light bulb by only making 1 trip upstairs.
