Richard J. ) gurgled happily, sounding much like
they were saying :

Not sure if anyone noticed this morning, but a major accident shut
the M25 anti-clockwise, near Heathrow.


I see that the lorry that crashed was a tanker carrying hydrogen
peroxide. Just as well it didn't crash into a tanker carrying
acetone.


That's a different accident which happen around noon today (30 August).
This thread was started yesterday (29th).


I can spot a conspiracy theory thread (or seventeen) starting about this
one...

Acetone's not that volatile, as organic liquids go. I used to
have, ooh... minutes of fun with an open wide-mouthed acetone container
and a thin tube ducked into a container of liquid nitrogen. The tube
would spit out small droplets of LN2 which would then skate around like
billiard balls on the surface of the acetone, leaving little vapour trails
to mark their passage. The limit was my boredom level, not the
disappearance of the acetone.

Well, no, but it is quite volatile as everyday liquids go. The more
volatile things tend not to stay around long enough to become everyday
items!

I'll have to try that.

You were cooling the acetone with liquid nitrogen, though, weren't you?
