Why don’t sheep shrink when it rains?

10 May

Sheep; cute little fuzzy berks in woolly jumpers.
We’ve all shrunk items in the wash, or at the very least seen it happen.  Woollen items cannot usually tolerate temperatures above 36° before the fibres begin to contract and ruin your best clothes.  Sad times indeed.
Lucky, then, that the average temperature of rain is just 31° – a standard delicate cycle on your washing machine, or a cool hand wash*.  Perfectly safe for woollen items like scarves or sheep.
* This is not true in hotter countries such as Chile, but they have alpacas and llamas over there and it’s obvious they come pre-shrunk.  How else did you think their necks grew that way?
