Stronger than glass, various military and commercial applications for this remarkable material are already being tested. What was once used in the science-fiction Star Trek movies, see-through aluminum is now something that - through test mixing with rubies, sapphires and more - is now being tried out in all kinds of ways to create transparency where strength is also required.
For now, it is used in static-free transparent aluminum wrapping for computer parts and other electronics. It is also being tested in otherwise-conventional see-through soda cans and military shielding for vehicles where windows once were. At over ten dollars per square inch, however, it is still not cheap enough for mainstream everyday use - but may be someday soon.
Now I'm not saying they should start manufacturing women's restrooms out of this stuff, but you've got to admit in this age of terrorism, bomb-proofing should be an important bathroom-security concern. Haha, see where I'm going with this? Home to get my video camera!
Thanks M_D, who invented invisible metal but The Fantastic Four bought the patent and buried it because they wanted The Invisible Woman to still feel special. *sniff* I'm sorry that was just so touching.
