While i am thinking about who remembers that experiment where you get some candles and float them in a wee boat thing and then place them inside an upside down bell jar to show the oxygen being burnt away and then the water rising up the glass.

I have been told that this is a fake experiment as if you do the calculations about oxygen being burnt and CO2 being produced you discover that it should only rise by about 0.02% the real reason is due to heating of air expanding and the escaping and then the air contracts and pulls up the water.

Correct me if i am wrong.

Thought We really should have an non empeg forum
