Ep 28. Engine Blocks, Jawbreakers, Drum Shells, Drums

How It's Made season 4 episode 28 takes viewers inside the factories where four different products are manufactured: engine blocks, jawbreakers, drum shells, and drums.

The episode begins with a look at the highly precise and complex process of creating engine blocks. Starting with raw aluminum pieces, the blocks are cast in molds that are specially designed to produce the intricate shapes necessary for high-performance engines. Viewers can watch as the blocks are machined, cooled, and polished to perfection, all with the goal of creating a durable and reliable engine component.

Next up is a visit to a candy factory where jawbreakers are made. The process starts with a mix of sugar, corn syrup, and flavorings that are heated and carefully blended to create a smooth candy mass. From there, the mixture is extruded onto a conveyor belt where it's shaped, colored, and stamped with the distinctive markings that make it a jawbreaker. Finally, the candy is cooled and packaged, and it's ready to be enjoyed by candy lovers everywhere.

The episode then moves on to drum shells, the essential building blocks of any drum kit. Viewers get a fascinating look at the process of creating high-quality drum shells from raw materials like maple, birch, and mahogany. They'll see how each piece of wood is carefully selected and shaped to create the perfect sound, and witness the intricate craftsmanship that goes into building a drum shell that can withstand the rigors of professional use.

Finally, the episode wraps up with a visit to a drum manufacturing plant where finished drum shells are turned into complete drum sets. From adding hardware and finishes to tuning and testing, viewers can see every step of the process that goes into creating a drum set that looks and sounds great.

Throughout the episode, viewers will learn not only how these products are made, but also the science and engineering behind their design and manufacture. They'll see how raw materials are transformed into finished products through a combination of skilled craftsmanship and cutting-edge technology, and gain a new appreciation for the work that goes into creating the everyday items that we often take for granted.
