with Johnny Ball
This week Johnny discovers the fun behind the facts when he says heaven preserve us!
He looks at preserved food, from the sun-soaked to the fresh-frozen.
Watch Johnny smoke a fish, salt a herring, squeeze a sausage and tin a can. Also discover how Napoleon kept his carrots and how Johnny gets into a pickle.
