Ep 10. Dial Thermometers, Hummus, Fuel Containers, Sombreros

How It's Made is a popular documentary series that showcases the manufacturing processes behind everyday items. Season 9 episode 10 explores the production of dial thermometers, hummus, fuel containers, and sombreros.

The episode begins by taking us inside a factory that produces dial thermometers. We see how these instruments are manufactured using precision machinery and skilled workers. From cutting and shaping metal components to assembling and calibrating the finished products, we gain an appreciation for the level of detail that goes into creating these temperature gauges. We also learn about the various types of thermometers available, such as bimetal, digital, and liquid-filled, and their many uses in fields like HVAC, automotive, and food service.

Next, we shift gears to the culinary world as we witness the creation of the popular Middle Eastern dip hummus. We follow the journey of chickpeas from their raw form to their transformation into a smooth and creamy spread. We see how other ingredients like tahini, garlic, and lemon are added and blended together to achieve the perfect balance of flavors. We also learn about the different varieties of hummus, such as roasted garlic, red pepper, and avocado, and how they are packaged and distributed to consumers.

Moving on, we visit a factory that produces fuel containers, which are essential for storing and transporting gasoline, diesel, and other petroleum products. We see how these containers are made from high-density polyethylene (HDPE) using a process called blow molding. We witness the raw resin pellets being melted and formed into a hollow tube, which is then inflated with compressed air to achieve the desired shape and size. We also learn about the safety measures that must be taken when handling these containers, such as storing them away from heat sources and static electricity.

Finally, we take a trip to Mexico to explore the traditional art of hat-making and the iconic sombrero. We learn about the history and cultural significance of this wide-brimmed hat, which has been worn by Mexican cowboys and musicians for centuries. We observe the intricate process of weaving palm leaves into the shape of a hat using various tools and techniques. We also discover the different types of sombreros available, such as the classic charro, the broad-brimmed jipi, and the festive mariachi, and how they are worn for different occasions.

Overall, this episode of How It's Made offers a fascinating glimpse into the inner workings of four very different industries and their unique production processes. Through expert narration and stunning visuals, we come away with a newfound appreciation for the everyday items that surround us and the skilled workers who make them.
