Fluorescein sodium salt and a little Rhodamine 6G in a glass tank. This is not interesting at all, the only “special” about this is that I got a flashlight for a few day from a friend and I tried it out with this.

The flashlight is a cheap Yongnuo YN-460 (~50 USD on eBay) what also emits some UV light what produces this nice green/red fluorescence with the fluorescent dyes.
