Make sure you don't soak the eggs too long, though, no more than the thirty
minutes. Eventually the vinegar starts leeching the calcium out of the
eggshell and you'll end up with a rather hilarous "rubber" egg. A new
flexible print medium? Apparently you can do the same thing with chicken
bones.

Great thread!
