Hello Manchester 

A crow perishing with thirst saw a pitcher, and hoping to find water, flew to it with great delight. When he reached it, he discovered to his grief that it contained so little water that he could not possibly reach the water. He tried everything he could think of to reach the water, but all his efforts were in vain. At last, he collected as many stones as he could carry and dropped them one by one with his beak into the pitcher, until he brought the water within his reach, and thus saved his life… 

The moral to this story 

Necessity is.

MOTHER OF INVENTION 

Come and quench your thirst!
