I remember the HUGE mercury thermometers in high-school science class that we'd "accidentally" break so we could get to that mercury and goof around with it!30% H2O2, full strength (~30%) ammonium hydroxide, strychnine, ferric chloride, iodine crystals, KCN, NaOH, Carbon Tetrachloride, quicksilver, and on and on. Now, a lot of these you need to go through special channels to buy.
