Concrete Room Riddle
You are in a concrete room. The room has no door, and no cracks in the wall. There is one small window with steel bars over it. The bars are too close together to even poke a finger through, much less your whole body. All of the walls, plus the ceiling and floor, are concrete that you cannot break through at all. You got in by magic, in case you were wondering. The only thing in the room is a wooden table. It is too heavy for you to lift. How do you escape???
