Ep 26. Glue

Modern Marvels is a documentary series that explores the history, technology, and science behind everyday objects and extraordinary inventions. In season 12, episode 26, titled "Glue," viewers are taken on a journey through the world of adhesives and learn about the various types and uses of this ubiquitous substance.

The episode begins with a look at the history of glue, starting with the ancient Egyptians who used a form of glue made from animal bones and hide. The narrator then takes viewers on a tour of a modern-day glue factory where they see how glue is made on a large scale. From there, the episode delves into the various types of adhesives available, such as epoxy, cyanoacrylate, and polyurethane.

To illustrate the strength and versatility of glue, the show features several real-world examples. For instance, we learn how glue was used to support one of the largest oil drilling platforms in the world in the Gulf of Mexico. The segment shows how industrial-strength epoxies were used to bond steel plates together on the ocean floor.

Another fascinating segment explores how glue is used in construction. We visit a job site where we see how glue is used to bond plywood to create hurricane-proof walls. We also learn how adhesives are used to create significant structures like the Burj Khalifa, the tallest building in the world. Finally, viewers are shown how adhesives are used in car manufacturing.

The episode also delves into the science of how adhesives work. Viewers will learn about surface energy and how it affects the ability of an adhesive to bond to a surface. We also see how glue can be engineered to work in specific situations, such as extreme heat or underwater.

The final portion of the episode looks at the future of adhesive technology. We see how researchers are using biomimicry to develop new adhesives based on the natural world, such as gecko feet and mussel glue. The episode ends with a look at the potential impact of these new adhesives, such as the ability to create stronger, more durable materials that use less energy to manufacture.

Overall, "Glue" is a fascinating episode of Modern Marvels that takes viewers on a comprehensive tour of the world of adhesives. From ancient Egyptian glue to modern-day glues used in construction and manufacturing, this episode has something for everyone. The show's engaging narration, informative interviews, and stunning visuals make it a must-watch for anyone who is curious about the science and technology behind everyday objects.
