Story of my life:
A third type of science project is simply trying to solve a problem that nobody really considers to be a problem. You’re doing it just for the Gee Whiz factor. For example, “If you have a pair of Bluetooth headphones, and you walk back into range of your computer, the computer can automatically unpause your music.” Yeah, I guess you could do that, but it also means that while you are away from your computer, you’re walking around looking like an idiot because you’re wearing headphones.
…yet still so fun!
