There is a man locked up in a room, which has no windows or any way out except for a firmly locked door that can’t be unlocked or destroyed by any means. There is an open tap at a corner of the room from which great amounts of water get into the room. What can the man do to escape from drowning, if he only has a large rope and a bucket that can hold up to 5 litres of water?
Answer
Turn the water tap off.
