About a year ago I remember seeing some pictures of a water cooled machine that had some type of UV reactive additive in the water to make all the tubing glow green. Any direction to where I can get more info on how this was done would be appreciated.
Personally, I just recieved my order from http://www.glowbottles.com yesterday. Check on eBay for this seller or email him for your specific needs. I paid $4 and some change (shipping included) for 3 bottles of dye and he sent me 4! I now have green, yellow, blue, and pink. Oddly enough, I wanted the pink dye the most but when it glows, it's orange...
Blue may be a little disappointing as it's nowhere near as bright as green or yellow.. nevertheless, some ppl have a bl00 fetish and I suppose it is all a matter of preference whether you want bright UV colors, or to keep to your blue color scheme.
