if you have an Iphone or droid you know all about gorilla glass.
Its the magic stuff that is incredibly durable.

Gorilla glass article although kind of long, it's fascinating.

Did you know it was invented in 1952 but Corning couldn't figure out what to do with the stuff until 7 years ago?

 

Very interesting! I've emailed the link to myself so I can read it in more depth later.

 

Wow, THAT was interesting. Makes me want to buy an iPhone; maybe some day when my $5/month cell phone no longer cuts it.
