My new favorite: fluorescent crystals at the side of a test tube.
Something new was made what crystallized on standing. Previously I could only make this compound as a powder and I was unable to grow crystals from it, since it’s nearly insoluble in everything, but now, with a little trick these nice crystals formed what are highly fluorescent and look great.

This purple bee balm is one of the most fantastically colored flowers I’ve ever photographed in UVIVF. Ordinarily green, with purple flowers and pinkish bracts, it’s a great variety of rich colors under my 365nm UV light. Each of the glowing nodes is a bud yet to bloom. For almost two weeks after photographing it, it kept blooming in a vase.
