Ep 23. Airstream Trailers, Horseradish, Industrial, Steam Boilers, Deodorant

How It's Made season 6 episode 23 takes a closer look at the production processes behind the creation of five diverse products, including Airstream Trailers, Horseradish, Industrial Steam Boilers, and Deodorant.

The episode begins with a look at the production of Airstream Trailers, the iconic silver bullet-shaped camper trailers that are instantly recognizable. These trailers are built using lightweight aluminum with rivets, which creates a strong and durable structure. We see how the company cuts sheets of aluminum to size, shapes and pieces them together, and then attaches the insulation and walls to the frame. The process of installing windows and appliances like refrigerators and toilets is also shown. The Airstream Trailers are a testament to American ingenuity and craftsmanship.

Next up is the production of Horseradish, a spicy condiment that is a staple of many cuisines around the world. We get a look at how horseradish is grown, harvested, and processed into the sauce we all know and love. The process begins with harvesting the horseradish root, which is then washed and grated. We see how vinegar and other ingredients are added to the grated horseradish to create the final product. Horseradish is a popular condiment that pairs well with meats and other savory dishes.

The episode then shifts gears to look at the production of Industrial Steam Boilers. These boilers are used to power a variety of industries including manufacturing, oil and gas, and food processing. We see how the boilers are constructed from large steel plates, which are cut, shaped, and welded together. The team also installs the burners that create the heat to power the boilers. Industrial steam boilers are vital to many industries, and this segment shows the complex nature of their production.

The fourth product featured in this episode is deodorant. Most of us use it daily, but we rarely think about how it's made. The episode shows us how sticks of deodorant are made, starting with heating and mixing the ingredients together in large vats. We see how the liquid mixture is poured into molds, cooled, and then cut to size. The process of adding fragrances to the deodorant is also shown. It's fascinating to see how a product that we take for granted is created from such simple ingredients.

Finally, we see how a range of fragrances are created for use in various products, including personal care items like deodorant. Using a combination of natural and synthetic ingredients, the fragrance makers create unique scents by blending base, middle, and top notes to create a complex aroma. It's amazing to see how the chemists are able to create such a wide variety of scents that can be used in everything from soap to perfume.

Overall, How It's Made season 6 episode 23 offers a fascinating look at the production processes behind a diverse range of products. From the iconic Airstream trailers to the humble stick of deodorant, the episode demonstrates the ingenuity and skill that goes into making the products we use every day.
