School ProjectsMostlySunny wibbles, "When I was 11 I got an A for my study of shark nets - mostly because I handed it in cut out in the shape of a shark."
Do people do projects that don't involve google-cut-paste any more? What fine tat have you glued together for teacher?

I had the same thing happenIn my Chemistry coursework. My hands were covered with black spots for over a week. Soap and water does nothing.
Aqua regis, if I remember rightly, is a mixture of acids. Nitric and Sulphuric I think.
Ammonia also removes it. Sadly this is a case of the cure being worse than the disease.
