string to a stone, and then, while holding the end of 

 the string in your hand, swing the stone round and 

 round, the stone is always, by action of this same 

 force, trying to fly off. And the faster you swing it 

 round the more the stone makes effort to get free ; 

 and if you let it go, it flies a long way. It is much 

 the same with the honey, as the comb which contains 

 it is swung round in the extractor. The difference is 

 that, as the capping is off the cells, the honey can get 

 free — instead of being confined, like the stone by the 

 string — and so is thrown out.
