Mad Labs

Enjoyment of this series depends entirely on your level of curiosity about any given product or process. Show me how chocolate is made and I'm yours for hours. Show me how vulcanised rubber comes into the world and watch the eyes glaze over. But sometimes things you never knew existed can inflame passions you never knew you had.

Like the series I Didn't Know That, Mad Labs is a grab bag of scientific trivia and technology. Tonight, we discover why hypodermic needles are about to get longer and scarier. Mad Labs also proves conclusively which way buttered toast falls, and what Scotsmen really wear under their kilts.

We also meet the Tennessee fainting goat, a most curious member of the farmyard family.
