Still, looks like you can still make a bunch of fun experiments in school? I've tried to engage my kids in some simple experiments (ph identification with cabbage, showing how bones can become brittle or rubbery depending on which components you remove, the classic soda&vinegar experiments etc).
University level treatment, dunno, seems like it should be fun but I had one chemistry class and balancing reductions is not that entertaining and that's most of it.
[0] I'm not sure of the actual English name, I mean those kits with a dozen things to combine, a becher, a Bunsen burner etc.
But yes, regardless of those two it should be easy to frame it as a magical adventure.
