but also, the days when your chemistry teacher could take you to the gun range
When i was in college i stole a bottle of mercury, and then while on a summer job stole two 500 ml bottles of fuming nitric acid from the industrial ceramics company i was working for (yes, that one)
Despite having no h2so4, I managed to nitrate enough mercury to convince myself that it was unnecessary to repeat the procedure. The amount needed to convince me? Less than a gram.
