As the process of cooling continued, the drop of water 

 voidd become a sid)stance of yet a different order, for there

 ing point was reached, the drop of water, through the action 

 of crystallization, would turn into a ball of ice. We should 

 thus see a puff of steam change from an invisible gas to a 

 vapor, from a vapor to a liquid, and from a liquid to a solid 

 body, and all through the simple process of cooling. 



The creation of a world is just as simple as that. Heat
