A childhood belief about around the house

In first grade, my class discussed fire safety and what to do if a fire starts in your home. One kid asked, "What if you don't get out of your house when there is a fire?" The teacher replied, "The firefighters would turn your room upside down looking for you." Well, I interpreted this literally. I envisioned a scuba-tank-looking pump that firefighters would hook up outside of your room, fill the space around the room with air, push a button, and voila, your room would literally turn upside down. That way, all of the furniture would fall to the ground and the firefighter would find you.
