CuSO4


Finally figured out why the flash on my brand new phone is not working, but Im glad I found it after I took the above photograph by mistake. The natural colour of the copper sulphate crystals showed up despite the lack of lighting, and my hand showed up grey for some strange reason. This looks like a great pped photograph, but it is actually just a combination of flaws in the device and tricks of the lighting. Ah well. PS anyone else notice rock salt growing into cubes, but never exactly making it there?
