CANDLE FLAME. 79 



A. Because the hot gases and air 

 (in their ascent) come in contact with 

 the hand placed above the flame : but 

 when the hand is placed below the 

 flame, or on one side, it only feels heat 

 from radiation. 



Q. Why is a RUSH LIGHT extinguished so 

 much more quickly than a cotton-wicked candle ? 



A. As the rush wick is smooth and 

 hard, the mere motion of the air 

 (produced by carrying the candle from 

 one place to another,) is sufficient to 

 sever the flame from the rush. 



Q. Why is it more difficult to blow out a 

 COTTON wick ? 



A. The cotton wick is quite full of 

 small threads or filaments, which help to 

 hold the flame on the wick, like the roots 

 of a tree. 



Q. Why does an EXTINGUISHER put a candle 

 out? 



A . Because the air in the extinguisher 

 is soon exhausted of its oxygen by the 

 flame : and when there is no oxygen to 

 support it, the flame goes out. 



Q. Why does not a candle set fire to a PIECE OF 

 PAPER twisted into an extinguisher, and usetl as such ?
