"It's more like, when I do experiments, it's on the kind of stuff that likes to blow up or catch fire or whatever, so we picked up the habit of not doing any experimenting on anything even vaguely dangerous without proper safety protocols, and it's still a good idea even if you're trying to do mostly-harmless magic because even mostly-harmless magic can set something on fire if you screw it up bad enough."
