How It's Made Season 6 Episode 10 giant valves, sardines, barographs, and disposable diapers

How It's Made is the fascinating television series that goes behind the scenes to show viewers exactly how various everyday objects are made. In season 6, episode 10, viewers are taken on a journey to learn about the manufacturing processes behind four very different products: giant valves, sardines, barographs, and disposable diapers.

First up in the episode are giant valves, which are used in a variety of industrial applications, from controlling water flow in hydroelectric dams to directing steam in a nuclear power plant. The show takes viewers on a tour of a valve factory, where they'll see giant blocks of metal being turned on lathes, cut and shaped with high-pressure water jets, and assembled by skilled technicians. With precision craftsmanship and strict quality control measures, these complex machines are built to last for decades, ensuring the safe operation of some of the country's most critical infrastructure.

Next, the show takes viewers to the coast of Portugal, where they'll witness the ancient art of sardine fishing. From the traditional wooden boats to the nets and hooks used to catch the fish, viewers get an up-close look at every aspect of sardine fishing, including the technique used to preserve the fish in cans. The cans are then loaded onto conveyor belts and sent through a series of ovens, where they are sterilized and cooked to ensure long-term shelf stability.

After a brief interlude at a music box factory, the show moves on to the production of barographs – scientific instruments that measure atmospheric pressure over time. Viewers will see how these machines are made, from the intricate clockwork mechanisms inside to the precision glass tubes that record the pressure changes. With precise engineering and careful calibration, these tools are used around the world to gather data on weather patterns and other natural phenomena.

Finally, the episode wraps up with a look at the manufacturing process behind disposable diapers. From the soft, absorbent materials used to keep babies dry to the elastic waistbands that keep the diapers snug, viewers will see how these lifesaving products are made on an industrial scale. With tens of millions of diapers produced each day, the factories that make them are some of the most high-tech and efficient in the world.

Overall, How It's Made season 6 episode 10 offers a fascinating glimpse into the world of manufacturing, as viewers get to see how these very different products are made. With a blend of science, engineering, and artistry on display, the show is a true celebration of human ingenuity and creativity.
