Ever wondered why the glass in your smartphone manages to survive all the wear and tear you put it through (or not)? It's all thanks to Gorilla glass - and guess what, it's old tech invented back in the 1960s.

Corning invented this stuff in the ’60s, but didn’t know what to do with it. Then a few years ago, someone showed a piece of it to Steve Jobs.
