That's the one.

Squirt some water into the exhaust then cut the top and bottom off a
tube of expanding foam adhesive and ram it in. You will need five
minutes or so for the effect to initiate. Half an hour would be best.
Repeat as necessary.

Those of us of a certain age will remember the Jennings book where a
potato rammed up the exhaust has the same effect.

Much cheaper than a tube of expanding foam,
and safer to use!

Boring... Pack his door locks with wet nitrogen tri-iodide.

In the north of England?

It would never dry out enough to be effective (although wet or dry, it
becomes unstable after a few days and go off when it feels like it)



Good point. Powdered aluminium and silver nitrate powder would be better -
if you could find a dry 5 minutes to install it...

Yes - my chemistry teacher was ex-ICI.

Nice stuff, had a test tube with rather a lot in in a locker, opened
the door one day to find it had changed state and the inside of the
locker was an interesting yellowish brown colour. Glad I wasn't around
when it did it...............




Ah, I had 1/2 " in the bottom of a jam jar full of water

It did, and I was



Big pop?

It was a look around to see if anyone had been injured moment, followed
by "how the **** am I going to get rid of that 6 foot circle of purple
off the ceiling"

Strangely enough, the top of the jam jar remained intact

It took my ears a few days to stop ringing
