Ep 13. Space Pens: Reef Aquariums; Metal Caskets: Composite Bike Wheels

How It's Made season 12 episode 13 explores the fascinating process behind the creation of four distinct products: space pens, coral reef aquariums, metal caskets, and composite bike wheels.

The episode begins by examining the space pen, a unique writing instrument designed for use in zero gravity environments. Viewers will learn how Fisher Space Pen Co. constructs each pen by hand, using a specialized ink and pressurized cartridge to ensure smooth writing in any atmosphere. The episode also takes a look at how NASA tested the pens before certifying them for use in space.

Next up is the creation of coral reef aquariums, which require a delicate balance of chemistry, engineering, and biology. The episode visits Marine Design Corporation, a company that uses computer modeling and specialized materials to build tanks that mimic the conditions of natural reefs. From there, the episode explores the intricate process of assembling and maintaining a successful coral reef ecosystem, including the use of live coral and saltwater chemistry.

The third segment of the episode focuses on metal caskets, which are manufactured by Aurora Casket Company using a combination of modern technology and traditional craftsmanship. Viewers will witness how skilled welders and fabricators assemble the caskets piece by piece, carefully fitting each component together by hand. The episode also examines the various materials used in metal casket construction, as well as the many customization options that customers can choose from.

Finally, the episode explores the process behind making composite bike wheels, which are renowned for their strength, durability, and speed. The segment showcases MAVIC, a company that builds bike wheels using highly specialized machinery and proprietary materials. Viewers will learn how carbon fibers are layered and treated to create a unique, lightweight frame that can withstand the harshest conditions. The episode also takes a closer look at the aerodynamic design of the wheels and the testing protocols used to ensure their quality.

Overall, How It's Made season 12 episode 13 is a fascinating glimpse into the complex and often surprising world of modern manufacturing. From the technical precision required to build space pens to the delicate care needed to cultivate coral reefs, viewers will gain a newfound appreciation for the skilled labor and intricate processes behind everyday objects.
