Ep 22. Steel Safes, False Teeth, Airplanes, Maple Syrup

How It's Made is an informative television series that takes viewers on a journey of discovering how everyday items we use are manufactured. In season 1 episode 22, viewers are taken behind the scenes to learn how Steel Safes, False Teeth, Airplanes, and Maple Syrup are produced.

The first half of the episode focuses on the production of Steel Safes. From small safes to large bank vaults, this segment shows how armoured metal sheets are bent, welded, and sliced to create secure containers. Viewers will see the various tools used in this process, including hydraulic presses, blow torches, and automated saws. The segment also delves into the safety features of steel safes, such as combination locks and electronic keypads, to ensure valuable documents, money, and other items are kept secure.

The second segment of the show explores the creation of False Teeth. From the initial impressions taken of a patient's mouth to the final product, this segment gives viewers an in-depth look at the process of making dentures. A variety of materials are used, including dental acrylic, porcelain, and resin, and viewers get to see how these materials are shaped and set to create prosthetic teeth. The segment also addresses how dentures are customised to fit a person's mouth and bite, and how they can be made to look more natural with the addition of gum tissue and tooth colouration.

The third segment of the episode takes viewers into the aviation industry, where they get to see how Airplanes are manufactured. The process begins with engineering and design, where 3D models are created and tested before any actual manufacturing takes place. Then, viewers see the assembly process, which includes the creation of the aircraft's wings, fuselage, and tail sections. Throughout the segment, viewers also learn about the materials used to make airplanes, such as lightweight aluminium and carbon fibre composite, and how these materials improve aircraft performance and efficiency.

Finally, the episode ends with a look at how Maple Syrup is made. Starting from the harvesting of sap from maple trees, viewers learn how the sap is boiled down to create the sweet syrup we all know and love. The segment also explores the various grades of maple syrup, from light and delicate to dark and robust, and how they are determined by factors such as time of year and the amount of boiling required. Viewers also get to see the unique tools used to harvest maple syrup, including spiles, buckets, and tapping trees.

Overall, season 1 episode 22 of How It's Made provides an engaging and educational look at the manufacturing processes behind Steel Safes, False Teeth, Airplanes, and Maple Syrup. From the intricate details of designing and testing airplanes to the centuries-old traditions of maple syrup production, viewers gain a new appreciation for the diligence, creativity, and innovation that goes into making the things we often take for granted.
