Here's a riddle to answer.
You are trapped in a small room, the room is plain nothing in it besides a single light bulb that illuminates the small room brightly and a small desk chair with wheels, the room has two connecting doors, one on each side of the room. One door opens to a maze of mirrors that would be impossible to navigate in the darkness. The other door opens to a room with a giant magnifying glass pointing in a straight direction, it's portable but very heavy for you to carry. Only one door can open at a time and you are slowly running out of light, darkness is growing fast. How do you get out?
