Here is a shameless plug for last week's kitchen science I have just finished writing up. I just think it benefits from a video.

There should be in the what may happen section. You will need Flash to see it. And to click on it to make it run.

all i get is the following text and what i presume to be a flash icon

Quote
When the plunger is pushed down very fast the cotton wool gets immensely hot and bursts into flames. This was used in the Burma, Malaysia Borneo region as a way of starting fires. These were made of horn or bamboo and would light a small piece of tinder. It is thought that Rudolf Diesel saw one of these and it gave him an idea..




i must have flash disabled somewhere............goes looking......

You are indeed perfectly correct in your guess ;)
There's a reason he's called daveshorts...

We had a fire piston as a demo at school. It was very impressive - a polycarbonate cylinder   into which you put a bit of oily 'fluff'.   You had to drive the piston down hard  and the fuel  would burst into flame  and push the piston back up. Problem was, I managed to blow up two of them, filled the room with flying shards and scared the kids.
We didn't buy a third one.

Was it one from cochranes? they seem to make theirs out of perspex, and I have broken one too. Mine is definitelt polycarbonate, as I built it.

Oh, I thought they were Rosy's legs. I'm relieved. I was beginning to think she must be a very, ahem, masculine girl...

(and hence potentially a contender for the Russian shot put team in the next Olympics...)
