Do you know what the strongest glass in the world would be? Would it be shatterproof and bulletproof? What would it look like and what would it take to eventually break it down?

One type of super sturdy glass is Tesla's Cybertruck windows. Who can forget when Elon Musk proudly boasted that it was unbreakable only to shatter it moments later?

Later on, the CEO explained that the glass lost its stability when the vehicle door was hit with a sledgehammer in an earlier part of the demonstration, and the glass itself is actually incredibly sturdy. 

It's referred to as Tesla Armor Glass and is described as an “ultra-strong glass and polymer-layered composite” that can absorb and redirect impact forces. The glass has also been described by Musk as transparent metal, but other than that, the exact engineering behind the material remains a mystery.

But Musk does not have a monopoly on tough glass. In 2011, researchers from Caltech and the Department of Energy’s Lawrence Berkeley National Laboratory introduced a metallic glass that was stronger and tougher than steel. Now, that's tough!
