We placed a jar upside down over a candle floating
in water. After the candle went out the water level 
in the jar suddenly rose.We think it may be because the 
oxygen was used up. But why didn't the water rise gradually 
while the candle was burning - was it because the air was 
hot and expanded for a while?
