A really quick post. What's changed in 3 weeks?
Not a lot.
New corrosion may be happening, but it's going so slowly that there's nothing really to show.
Thus, another rethink (or perhaps "threethink" at this point). I was so busy narrowing things down that I think I lost sight of the forest. The beach isn't one event, it's a system. It's sand, wind, salty air, wet times when the tide comes in, starkly dry times when it goes out. People kicking things around, burying them. It's dynamic, unpredictable. It's not a can sitting in a bucket of water on a countertop for a month.
So, my rethink: Make a soda can experience real beach conditions. A can should be drunk, crushed, shaken around in wet sand, shaken around in dry sand, tumbled, rolled, exposed to bright light, buried. Only by doing that will I be able to say whether it was a beach environment that causes a can to rot like those that I've collected.
More to follow!
