How Not to Do It: Liquid Oxygen Cylinders (pipeline.corante.com)

Wow, and Darwin came up empty-handed. Amazing. Blew a O2 dewar in their truck, crashed through an apartment, broke a gas line, and no deaths.

This reminds me of high school: "Chemistry teachers have all the fun." It seems like they have all made a deal with the devil (or school board... which may be redundant): covalent bonds, redox equations, and titration are boring beyond all speaking of it. None of you want to teach it. I'll teach it. In return, you will give me a materials budget, and I will blow stuff up.

This reminds me of the students who attempted to flush an elemental Lithium compound down a toilet. Lithium is extremely reactive in an exothermic manner with water. Lithium floats.
