Off subject a bit, theres another little demo that the teacher did. It was an ammonia fountain, I pretty sure he told me had luminol in the mixture.
When the light were turned off it glowed as the liquid would fountain up through a tube into inverted r/b flask.
I cant remember what the other demo was cause it was kinda boring compared to a lot of other things, teachers aren't allowed to do much anymore for
demo.
