Someone asked a few days ago, that what is my favorite chemical reaction.
So here is it. When we place a piece of copper wire to a silver (nitrate/sulfate) solution beautiful silver crystals will start to grow on the surface of the copper, while the copper dissolves into the solution.
I have made this experiment for nearly a month, but it was worth, adorable silver crystals formed!
Anyone wants a hi-res from them? Just send a mail address and let me know the chosen picture(s).
