I'm sitting in a hotel restaurant having lunch with my mom. We hear a rumble sound and the walls shake. I look out the window to see big chunks of concrete sidewalk pushed up in the air like a newly forming mountain range. I conclude that water in the ground under the sidewalk has frozen and expanded, pushing the concrete up. Somehow this has knocked the hotel's elevator air filtering system offline. They hire me to design and build a new one that is made from easy to find parts and can be maintained by someone with no experience. Right now they only need one so that people can get down from the many stories above. My friends and I build it inside of an elevator and we ride up and down with it to make sure it continues to work as people move around the floors. One part had to be cast out of metal by my dad, scaled up from a prototype I sent him. I'm worried that this violates the off-the-shelf parts requirement, but I figure the part is painted bright red so no one will notice.
