Do people do projects that don't involve google-cut-paste any more? What fine tat have you glued together for teacher?

when the solution dries out......the silver nitrate crystals left behind darken on exposure to light. It's used (or was used, dunno if it still is) in photography.
You can google "silver nitrate stain" to get an idea. Now imagine a metric fuckton of it all over everywhere, taking into account it's not the cheapest stuff to buy large quantities of.
