Ep 10. Holograms, Package Printing, Skin Cultures, Canned Corn

In season 1, episode 10 of the popular show "How It's Made," viewers are taken on a fascinating journey into the world of holograms, package printing, skin cultures, and canned corn. From the intricate process of creating holograms to the technology behind printing packaging designs onto materials, this episode offers a behind-the-scenes look at some of the most important and intriguing manufacturing processes used in today's world.

The episode starts off with a look at the production process behind holograms, which are 3D images that are created by recording the interference pattern of a laser beam. Viewers get to see how holograms are produced step by step, starting with a glass plate that is coated in photo-sensitive material. As the laser beam is directed onto the plate, it records the interference pattern and creates the hologram image. The hologram is then coated in aluminum to give it the reflective qualities that make it so stunning.

Next, viewers are taken on a tour of a package printing facility, where advanced technology is used to print designs onto a wide variety of packaging materials. The printing process involves four colors - cyan, magenta, yellow, and black - which are mixed in different combinations to create a full-color image. Intriguingly, the printing process also includes an inspection system that uses sensors to detect any defects in the printed image and automatically corrects them.

The episode then moves on to skin cultures, which are used by scientists to study skin biology and develop new treatments for skin disorders. Skin cultures are created by taking a small sample of skin tissue and placing it in a petri dish filled with a nutrient-rich medium. The cells in the tissue then divide and grow, creating a skin culture that can be used for further study. The skin cultures are particularly useful in studying conditions like eczema and psoriasis, as they allow researchers to test potential treatments without putting patients at risk.

Finally, the episode concludes with a look at the process behind canned corn, one of the most popular canned vegetables in the world. Viewers get to see how corn kernels are harvested, washed, and transported before being blanched and canned. The canning process involves filling the cans with a mixture of corn, water, and salt before sealing them in a vacuum-sealed chamber. The cans are then heated in a retort, which kills any bacteria and ensures that the corn is safe for consumption for extended periods.

Overall, season 1, episode 10 of "How It's Made" offers a fascinating look into the worlds of holograms, package printing, skin cultures, and canned corn. From the intricate and precise processes used to produce holograms to the advanced technology used in package printing, this episode is sure to amaze viewers with its insights into some of the most important manufacturing processes of our time. And with a focus on skin cultures and canned corn, the episode also highlights the practical applications of these processes and their impact on society as a whole.
