Just one of dozens of amazing passages in this book (page 48):

> "... its density was a little better than that of the other acid, and it was magnificently hypergolic with many fuels. (I used to take advantage of this property when somebody came into my lab looking for a job. At an inconspicuous signal, one of my henchmen would drop the finger of an old rubber glove into a flask containing about 100 cc of mixed acid -and then stand back. The rubber would swell and squirm for a moment, and then a magnificent rocket-like jet of flame would rise from the flask, with appropriate hissing noises. I could usually tell from the candidate's demeanor whether he had the sort of nervous system desirable in a propellant chemist.)"

I think it's a bimodal distribution. On the one hand you have the unflappable who just calmly watch what happens. On the other you have the far too flappable who is already out of the lab and making good time out of the building and the state.

Although for some reactions, the latter is the appropriate reaction.

Exactly this. Either they have the right stuff, or they don't.

Ah so this is where the cartoon trope of jets of boiling fluid speeding up from a lab flask came from. I thought artists were exaggerating, but I guess not this time.
