Hey guys,

today, I want to show you some crystals for the #sciencepic initiative.
The first ones are crystals of table salt (sodium chloride NaCl) which grew in a colleague's washing solution.
Perhaps you know, that table salt tends to crystallize in the shape of little cubes. Normally, you can see them with a microscope, but if you let them grow, they can be easily seen with the naked eye.

The second crystals are of bromo pyrene (C₁₆H₉Br), which was sythesized by another colleague. They look like a mixture of little needles and lamina. Sadly, the color is not that nice, I think.

When I saw these nice results, I felt like I should do crystal growth again. I will show you some pictures of the results soon.

Edit: In case, you don't know how bromo pyrene looks like, I add you the structure here:
