Extro: A mountain of washing machines.

3. The Secret Life of the Sewing Machine
The first patent for a sewing machine was taken out by an English cabinetmaker called Thomas Saint in 1790. It's doubtful whether he actually built his design, because, when one was made from his drawings 100 years later, it had to be extensively modified to work. Episode Contents: Models: A giant human powered lock stitcher demonstrates the basic idea. A cut away singer shows how a crank powers all the basic functions. A demonstration of cams and stepper motors. Machines: Three of Tim's famous collecting boxes: The head scratching curator the rubber-necked guard and the doctor that writes out illegible prescriptions. There are some brief close ups of the construction of these machines. Rex also shows his magical remote controlled suitcase. Guests: A thumb crushing Thimmonier (the 1st practical sewing machine) Many antique decorative sewing machines. Films: The old Singer advert from the 40's is probably the funniest clip in this series. Extro: Say it in thread.

5. The Secret Life of the Central Heating System
At first Roman houses simply had a fire in the middle of the room (the Latin for hearth is focus). But they probably had trouble with smoke as the Latin for living room is atrium (from ater meaning black). By about 400AD the Romans had perfected a form of central heating. The fire was lit outside in a furnace with hot air ducts under the floors and in the walls. Episode Contents: Models: Trying to start a fire with an electric drill. A Norman chimney vs a proper one. A life size 2 dimensional house model with radiators and boiler. A glass radiator. A balanced flue. Machines: Jacob's ladders by Rex. Guests: Solid fuel, oil and natural gas boilers. Films: Yet another silly 40's promotional film, this one for the Ascot gas boiler. Extro: The model house springs a leak.

6. The Secret Life of the Television Set
John Logie Baird, the Scottish inventor, developed an electromechanical TV system in the 1920s and gave frequent public demonstrations. The publicity encouraged EMI to develop a practical all-electronic system, similar to today's. In 1936 the BBC transmitted both systems, but EMI's was judged superior. Episode Contents: Models: TV scanning is demonstrated with a drawing made on many strands of string. A cutaway TV and cards that mimic the screening of a colour TV. Explanation of the simplest electronic components. Machines: Tim's displays at the National Film and Television Museum (UK) Guests: British TV sets from before and after WWII.
