Just to act on the dumb side. If you use a graduated beaker with a candle  
in it, add the water, and the second beaker, and then measure the water  
height. Shouldn't the increase in temperature in the up-turned beaker  
create a high-pressure that forces the water out from under it and thus an  
increase in the water height as measured in the graduated beaker? So why  
is the level of water forced out by the high-pressure less than the amount  
'sucked' in by the low-pressure?
