Watch this video, it’s pretty cool, and shows you some of the niches that hobbies have
Joshua Finn makes F1D model airplanes. These planes can fly for up to 30 minutes on the winding of a single rubber band. You know the these guys are serious when they start to describe the uniqueness of different vintages of rubber bands. Specifically rubber from May of 1999. I’m sure someone with an engineering degree could provide some verification to that, but I’ll believe them. I’m not making fun of these people at all. It’s a really interesting hobby, and if I had time, I’d get into it, but with all the other things that I spend my time doing, I don’t think I’d ever be able to dedicate enough time to do it correctly.
