Hey jeff247! Thanks for the question, though now I have to admit that yes, I have accidentaly had a (small) explosion. Quite a while ago, I was clearing up some old samples in the lab, when I accidentaly squirted some water onto a lump of sodium (I didn’t realise it was there).
Now if you haven’t seen sodium react with water, this is the kind of thing that happens!
Now, thankfully it was in a fume cupboard, so nothing bad happened, but there were some big flames! It was a good reminder of how reactive some of our materials are.
