Riddle of the day
Imagine you are in a room with 3 switches. In an adjacent room there are 3 bulbs (let’s say in lamps which are on a regular table), each switch belongs to one bulb. All are off at the moment. It is impossible to see from one room to another. No help from anybody else is allowed.
How can you find out which switch belongs to which bulb, if you may enter the room with the bulbs only once?

Is this it? You turn two of the switches on, leaving them on for a couple of minutes. Then you turn one of the switches off and walk into the adjacent room. In the room with the lamps, one bulb will be on (the one you switched on and left on), one bulb will be off but warm (the one you switched on and then off again), and one will be off and cool (the switch left off). Man I’m a genius. Next riddle beeatch.
