Ep 7. Speed skates, synthetic rubber, cocoa beans, and bulk chocolate

How It's Made Season 10 Episode 7 takes us on a journey through the creation of four very different products: speed skates, synthetic rubber, cocoa beans, and bulk chocolate.

The episode begins with the production of speed skates, which requires the use of a variety of machines and tools. We see how the blades are shaped and sharpened, how the boots are molded to fit the athlete perfectly, and how the laces and straps are added for support. We also learn about the importance of aerodynamics when it comes to speed skating and how even small changes to the shape of the skate can have a big impact on an athlete's performance.

Next, we take a look at the process of making synthetic rubber. This involves the use of complex chemical reactions to create a material that has similar properties to natural rubber but can be produced more efficiently and at a lower cost. We see how the various chemicals are combined, how the material is heated and molded into shape, and how it is tested to ensure that it meets strict quality standards.

Moving on, we learn about the production of cocoa beans and the important role that they play in the chocolate industry. We see how the beans are harvested, sorted, and roasted to bring out their rich flavor and aroma. We also learn about the various grades of cocoa beans and the different characteristics that make them suitable for different types of chocolate.

Finally, we are taken through the process of making bulk chocolate, starting with the grinding of the cocoa beans into a fine powder. We see how sugar, milk powder, and other ingredients are added to create the desired flavor and texture, and how the mixture is heated and cooled to create the finished product. We also learn about the various forms that chocolate can take, from bars and chips to powders and syrups.

Throughout the episode, we are treated to fascinating insights into the world of manufacturing and the tremendous amount of skill and expertise that goes into making everyday products that we often take for granted. Whether you are a fan of sports equipment, chemical engineering, or sweet treats, How It's Made Season 10 Episode 7 has something for everyone.
