The second season of How It's Made continues with its 18th episode, showcasing the production processes of four very different products: Grinding Wheels, Compost, Window Blinds, and Milk. Each segment of the episode delves into the intricacies of manufacturing and highlights the behind-the-scenes efforts that go into creating everyday items.

The episode begins with Grinding Wheels, which are essential tools in many industries, including construction and manufacturing. Viewers get a glimpse into the detailed process of crafting the wheels from scratch, starting with the mixing of abrasive materials such as aluminum oxide or silicon carbide with bonding agents. After shaping and curing, the wheels are put through various tests to ensure they can withstand the rigorous conditions for which they are intended.

Next up is Compost, which takes viewers into the world of organic waste management. Starting with the collection of food and yard waste, the show explores the process of turning the waste into nutrient-rich compost. Viewers get to see the various ingredients that go into the compost, such as wood chips and straw, as well as the machinery used to mix and turn the compost over time. The final product is a dark, crumbly substance that can be used to fertilize plants and gardens.

The third segment focuses on Window Blinds, a ubiquitous household item that few people stop to consider how they are made. The episode explores the different types of blinds (such as venetian, roller, and vertical), as well as the various materials used to manufacture them, from plastic to wood to aluminum. Viewers get to see the process of cutting and shaping the materials, as well as the intricate machinery used to assemble the blinds. The segment also highlights the numerous safety measures in place during production to ensure that the blinds meet strict industry standards.

Finally, the episode wraps up with a look at Milk, a staple of many people's diets. The segment shows the complex process of bringing milk from the cow to the table, starting with the milking process and moving on to the testing and pasteurization of the milk. The episode also delves into the different types of milk, such as skim and whole, and the different processes used to create them.

Throughout the episode, viewers are treated to fascinating facts and figures about each product, as well as interviews with the experts who create and manufacture them. How It's Made season 2 episode 18 is an excellent showcase of the dedication, skill, and ingenuity required to make the products that we use every day.
