Which switch is which?
There are three light switches outside of a room.
Labelled number one, number two, and number three.
The door to the room is closed and you can’t see in.
All three switches are off.
You need to figure out which switch (outside) belongs to which bulb (inside).
You can use the switches however you want to, but can only enter the room once. How do you do it?
