We had a litttle accident at home today which prompted Shawn to do an online search. Here's what he found. I especially like this part:
"Pennies minted before 1982, which are 95 per cent copper and 5 per cent zinc, showed no erosion. However, those minted after 1982, which are nearly all zinc, with a thin copper plating, began eroding immediately. By the second day, they had holes in them. The researchers found the zinc in the coins reacted with the acid to form hydrogen gas and zinc chloride. The reaction, similar to the chemical process that occurs in car batteries, can erode the stomach lining, causing an ulcer."
Damn, I knew I should've checked the date on that penny before Jax ingested it this afternoon.
