At CES 2011, Corning was showing off their Gorilla Glass product, which is used on many mobile devices you may know, like the entire Samsung Galaxy S and Tab line, most Motorola Android phones, all Dell mobile devices, the LG Optimus 7, and others. Gorilla Glass is not only very strong when it comes to impacts that would normally crack your display (like a fall), but it’s also incredibly scratch resistant. In this video, we take a razor-sharp kitchen knife to a Samsung Captivate, and find it impossible to scratch the screen, even with a heavy amount of pressure. Impressive.
