Paul: If you put a candle in a jamjar, it will burn. If you put the lid on, the flame is starved of oxygen, and then is extinguished. If you put this cottage over the candle, the flame will go out because there is no oxygen. If the chimney were patent (open, thank you flying free!!) then there would be an orifice (that's an opening!) for the smoke to escape and the oxygen to enter and feed the flame!! :usd:
flying free: That is quite a serious condition for a little newborn baby, and is much less common in boys, I do hope he is alright now.
Biology and science lessons over....who made this little cottage PLEASE?
