I grew some epsom salt crystals in a jar. I saturated hot water with the crystals, poured some in a jar, and set the jar on a shelf for about a week.

I placed a small piece of purple sponge in the jar, which made the photos a little more interesting. Here is a photo of the jar:
Here are 8x photos of the crystals, just using my wife's cell phone camera:
