One small chemistry point: 91% isopropyl alcohol with 9% water is an azeotrope, a mixture that boils at a constant point. When it evaporates, it...
I'm pretty sure it's "3 posts, 1 idea per post". Sorry for nitpicking. I'm a programmer -- it's like being a lawyer, only more so. :)
I'll have to think about this one for a bit. I do see one problem with the rules as they stand: if someone lists three ideas in one post, how...
I see a turtle. [ATTACH]
90% silver coins. I'm feeling better about the small pile I sold over the weekend... for once. :)
Tell me more about these mines that have a big "Silver/Gold" switch stationed by the entrance. :)
The dealer was also finishing up a large buy from someone else, so things were a little hectic. I think, though, that most coin dealers in a...

Well, magnets do pose a bit of a hazard, but it's less than you might think, and decreasing as technology advances. Color CRT monitors would be...
This probably goes without saying, but if you do carry a magnet with you, be sure to keep it away from any credit cards, membership cards, or...
The folks arguing against end-times hoarding of PMs always say "you can't eat gold and silver", but THIS is taking that argument a little too far...
The thing is, if an image is displayed in your browser, you've already downloaded it. At that point, it's just a matter of how convenient it is to...
But all of life takes place in the grey area between "absolute certainty" and "complete unpredictability". You can't be absolutely certain that...
I'm still trying to figure out how one would go about uttering (passing) an image of currency displayed on a Web page.
