Ok, check this out - lil on the odd side eh? The fluid is radiator coolant. I was hoping it would glow more under the lights - but I think I know why it doesn't, the bottle I picked up states "Safe for all colors of coolant" which means the bright green stuff around before 1995 and the new orange stuff used 1996+. I'm going to go try to track down the older stuff and see what I can do with that. I picked up a whole slew of different bottles and scientific stuff from the surplus store, want to see if I can't do something with it. C & C welcome as always.
