It's really scary how absolutely "dumb as a box of rocks", stupid - you people are. Not a single concept of what something is or what it's used for. As long as that blackberry sends texts and your poptarts are hot - just cruise down the highway of life. I hold out little hope that you're actually going to learn something, but visit United Nuclear (Google, it's a search engine). They use a lot of big words, but the Cliffs notes version for the ADD crowd - they sell science supplies to TEACH chemistry and physics. They're one of the last companies that haven't bowed to the Patriot Act since some things they sell can be "bad". Hard science and chemistry at the High School level is almost non-existant. We used to blow ***** up. Yes, you could get hurt if you didn't follow instructions. Now days, mommie and daddie would be suing the hell out of everyone for exposing their precious little ***** to something called knowledge. Ah. ***** it. What's the use with you ***** anyway. Bury away. A least I'll probably be dead before any of you are in any positions that can totally ***** everything up.
