So, I've thought about this for awhile now an mentioned it on the server once. I think it would be a really awesome if you guys added this to chemistry...
The recipe would create a "Glowing Liquid" similar to that you would find in glow sticks
These could serve as a weaker substitute for flash lights in a pinch. It could if desired be slightly radioactive or toxic when consumed or injected. I can't imagine it causing any balancing issues, and would only add another little cool feature to an already impressively unique server, adding to gameplay as a whole.
