[Darkroom] Hello and looking for liquid bromine

This is sounding promising.  What can I do to help?  I'd be happy to bring my daguerreotype skills into the fray.

The chemical companies will definitely sell to educational entities, but they're looking for a chemistry lab component--they're more used to dealing w/ college purchasing departments.  Might I suggest it's worth putting a very strong foot forward when talking to them, a la a plan?  A rejection can equal blacklisting. 

Intelligent persistence will get us all what we want.  Say, Ben, you being in possession of some bromine, are you a chemistry wiz like Jasmine?  I do like your science demo idea a lot.
