There is a room which has one lamp inside and three switches outside. One of these switches is the one that lights the lamp. You have only one attempt to find the right switch. Which switch or switches must be pressed so that when you open the door you will figure out which is the right one, given that when the door is closed you can’t see if the lamp lights or not?

  1. 1. Fill the 5L container from the flask, fill the 3L container from the 5L, leaving 2L.

Refill the 5L container from the flask, then top off the 3L container with 1L from the 5L container.

    5. Turn the first switch on for 5 minutes, then turn on the second and walk into the room. If the light is on, the second switch controls it. If it is off but hot, the first switch controls it. And if it is off and cool, the third switch.
