I was thoroughly entertained by this bit of hobby chemical sleuthing from Michael August Pusateri, who observed years ago, while bored on-shift, that the hot sauce at the fast food joint where he was working would clean the oxide off a penny. My immediate assumption–that the effect is due to vinegar or some other acid in the sauce–turns out to be only half right. The right answer, and the process by which Michael arrived at and verified it, make for interesting reading. You might even find a use for it.
A Seattle family exposed to the virulent penny floor meme has contracted a more expensive (and therefore probably less contagious) mutant strain that metabolizes nickels instead of pennies. I do like the different color effect this achieves, but by my math (and depending on how much space you leave between the coins) penny flooring costs between $2.50 and $3.00 per square foot, whereas nickel flooring costs four times as much ($10-$12). I did not bother to compute costs for quarter-, dime- (ouch), or Sacagawea dollar-flooring, on the assumption that no one would ever go there. But if they do, please, nobody tell me about it.
