Bricked up room
You are in a room that is completly bricked in on all four sides, including the cieling and floor. You have nothing but a mirror and a wooden table in the room with you.
How do you get out?
You look in the mirror you see what you saw, you take the saw and you cut the table in half, two halfs make a whole, and you climb out the hole. :)
