Yesterday news broke that Apple was dropping some coin into a project to build a new manufacturing facility in Arizona. The facility would be built by GT Advanced Technologies to create Sapphire glass for iPhones. The glass is pretty much as strong as diamonds and scratch resistant.

A new video circulating the Internet takes us inside GT Advanced Technologies and gives us a first hand look at the sapphire glass creation process. Think of it as a Mr. Rodgers road trip for tech nerds. It’s worth checking out.
