WOW! What ever you need and want let me know and I'll hook you up at a good price.

Seriously though, if it really is the end of the world, then you are not safe anywhere on it. Lava melts just about anything on this planet. If you want glass to block water, just get yourself some glass panels about 8 inches thick, it should cover you against fast moving water and should hold up should you be under deep water for some time at intense pressure. But the Lava melts the glass, so you might want another alternative. Bio Suit, look them up online. There's a variety of different suits with different lifespans and shelf life. They can cost you from a few bucks to a few hundred or even thousand depending how high-tech you want to get with them. As far as Nibiru goes, I don't know how to protect against ficticious planets. In the long run, your best bet might be to build a space ship instead and high-tail it to Mars. You'll probably be safer there.

*sigh* I can see someone out there using this 2012 junk to take advantage of poor naive fools and make a lot of money off of them. As for me, if it is the end and it is our destiny there's nothing we can do about it. But I'm not about to panic and worry about it, instead I'll live my life till then and welcome it when the time comes on a lawn chair in my yard wearing some shorts, a wife-beater, and some flip-flops with a beer in my hand.
