[Darkroom] Hello and looking for liquid bromine

[Ben Rupert]

I might have some liquid bromine, I'll check and get back to the list.
Also I didn't watch the video on electrolytic bromine generation, but I
have a power supply made for electroplating metals which should work for
oxidizing Br- to Br2.
