Machines! S01 E08 Thames Flood Barrier, Electric Locomotive, Gas Pump, Photo-finish camera

Machines! is a detailed, entertaining and "wow-fact" half-hour on how machines work. By using photo-real computer animation we are able to go where no camera can fit, or even survive. Entertaining, engaging and easy-to-understand commentary untangles complex design and engineering for all ages, while having some fun along the way.
