We did all sorts of stuff in high school chemistry and physics that would cause heart attacks in administrations and parents for miles around. We survived and learned. Kids are too coddled today.

Mercury is REALLY bad news for aluminium, because it breaks down the oxide film that prevents aluminium behaving in air as the highly-reactive metal it actually is. Not quite as reactive as sodium, but not far off. Oxidation proceeds very rapidly and what was aluminium becomes a fine powder of alumina - aluminium oxide, china clay. So don't even think about taking mercury on a plane! -- OOO - Own Opinions Only.
