So you got a marshmallow, a pop sock, and a plank of good ol' wood. You're in a metal room with welded walls and doors, ceilings, and floors. THERE IS NO WAY OUT. But you CAN get out. How?
Answer: You rip the marshmallow in half to get a marsh, then surf across the marsh on the plank of good ol'wood with your amazing skills, then you rip a hole in the pop sock and climb out of the hole.
