I'm not sure what you were planning to do with the next 24 minutes (16 if you watch at 1.5 speed like I do with most talking-heavy videos) of your life, but I have a good suggestion: Smarter Every Day's video about building a supersonic baseball cannon. This episode is actually fairly light on explaining the underlying science that is often a part of his other videos. There's more of than in the one-hour making of video.
This video just mentions a few things in passing like Schlieren imaging and mach angles. These are concepts that were initially used in this his previous video about imaging the shockwaves of bullet.
If you find this sort of thing interesting, I recommend supporting Smarter Every Day on Patreon. I do.
