Ep 7. Pressure Cookers, Mechanical Singing Birds, Oceanographic Buoys and Stainless Steel Tank Trailers

How It's Made Season 7 Episode 7 explores the creation of Pressure Cookers, Mechanical Singing Birds, Oceanographic Buoys, and Stainless Steel Tank Trailers. In this episode, viewers are taken through the manufacturing process of these unique products.

First, the show looks at the production of pressure cookers, an essential kitchen appliance that has been in use for many years. The process of making pressure cookers involves using high-quality stainless steel to create the main body of the appliance. Once the steel has been cut and shaped, it is welded together to form the cooking pot. Next, the handles and lid are added, along with the pressure regulating mechanism which makes it possible for the cooker to maintain a specific pressure level. Finally, the cooker is tested to ensure that it meets all safety standards.

Moving onto Mechanical Singing Birds, the show explores how these intricate and delicate creatures are brought to life. Mechanical singing birds are small, clockwork contraptions that use a system of bellows and pipes to create realistic bird sounds. The body of the bird is made from a combination of metal and delicate feathers which are attached by hand. The bird is then filled with clockwork mechanisms, and the final product is tested to ensure that it moves and sings like a real bird.

Oceanographic Buoys are the next product to be examined on the show. Oceanographic buoys are used to gather data on the ocean's temperature, currents, and other important information. The production of these buoys involves using a combination of plastic and metal parts to create a buoy that can withstand harsh ocean conditions. The buoy is fitted with a range of sensors and data collection devices which are capable of transmitting data back to scientists onshore.

Finally, the show concludes with a look at the production of Stainless Steel Tank Trailers, which are used to transport liquids such as milk, water, or oil. The process of creating these tank trailers involves using high-quality stainless steel to create the tank, which is then attached to a trailer chassis. The tank is fitted with a range of pipes and valves to ensure that the liquids are transported safely and efficiently. The tank trailer is then tested to ensure that it meets all safety and performance standards.

Overall, How It's Made Season 7 Episode 7 provides a fascinating insight into the manufacturing processes of four very different products. From pressure cookers to oceanographic buoys, viewers are sure to be entertained and educated by this informative and well-produced series.
