Ep 12. Composite Propane Cylinders, Salsa, Water-Pumping Windmilles, Dragsters

How It's Made season 9 episode 12 gives viewers an inside look at the manufacturing process of a variety of products ranging from composite propane cylinders to dragsters.

The episode starts with composite propane cylinders, which are a popular alternative to traditional steel cylinders. The manufacturing process of these cylinders involves using a resin and a reinforcing fiber to create a thermoplastic composite material that is lightweight and corrosion-resistant. The raw materials are mixed together and then extruded into a cylinder shape using a special machine. The cylinders are then cured in an oven to harden the material and ensure that they are safe for use.

Moving on to a more savory product, the episode delves into the production of salsa. Viewers are shown the process of making a basic tomato-based salsa, which involves cutting and dicing fresh vegetables and adding them to a large mixing bowl. The vegetables are then mixed together with various seasonings and spices before being jarred and sealed for distribution.

Next up are water-pumping windmills, which are used to pump water from underground wells for irrigation or livestock watering purposes. The manufacturing process of these windmills involves casting various parts, such as the hub, tail, and spokes, from iron or steel. The blades are typically made from wood and are attached to the hub using bolts. Once assembled, the windmill is tested to ensure that it is generating enough power to turn the water pump.

Finally, the episode explores the world of drag racing and the manufacturing process of dragsters. These high-performance race cars are designed and built to go extremely fast, with some being capable of reaching speeds of over 300 mph. The manufacturing process of a dragster involves creating a tube chassis, which is then covered in a fiberglass or carbon fiber body. The engine, which is typically a high-powered V8, is then installed and the car is tested and tuned to ensure that it is running at peak performance.

Overall, How It's Made season 9 episode 12 provides a fascinating glimpse into the manufacturing processes of a diverse range of products, from everyday items like salsa to high-performance vehicles like dragsters. Viewers are sure to be impressed by the level of precision and attention to detail that goes into creating these products, and may even gain a new appreciation for the things they use and consume on a daily basis.
