Purposely deteriorating zinc pennies

[Pull tab mcfoilson]

I was out detecting w my son and was explaining to him how cheap today's pennies are and how they deteriorate so fast.

We had the idea to put em in a cup w some salt and watch them deteriorate over time.

Do you guys have any ideas of what else we should pour on them to watch them dissolve lol?

The ones I found in the driveway were destroyed by the car exhaust. I saw one on a salt water beach, I parked in the same spot the day before and it wasn't there. In one day (heavy salt spray that night), it was starting to deteriorate already.
