Instructions
Go to your dorm room and use two crates from your inventory. Place the crates side-by-side on the floor.
Select two rugs -- a small one and a large one -- from your inventory.
Position the small rug on the floor so that its edge touches the edge of the large rug.
Place the small rug atop the two crates.
Move both crates away from the small rug. It will float in the air and allow you to fly out of your dorm room.
