I think the tech inspectors are just looking for the dye colors used to mark the three current types of anti-freeze.
So maybe it's as simple as drawing up a bit into a tube with a white card behind and making sure there aren't any "banned" colors.
I guess you could print up some card stock with squares of "banned" colors and use it with those bulb-and-tube arrangements used to test antifreeze specific gravity.
It could also just be a matter of getting a few drops on your finger and thumb and "feeling" for slipperyness". It's a distinctive feel.
[edit] LC is right - a refractometer is the way to go. Unsure if the non-glycol solutions would change refraction, but it would be easy enough to test. I never saw one of these at the track, though - but I never got past being an amateur[/edit]

BTW, I dropped a bike on an antifreeze spill once (but on a public road). A cop stopped and got out of his cruiser with ticket-tablet in hand (guess he was going to write me up for being reckless or something) but then he fell down. It's very slippery.
Oh - and no, I didn't get a ticket.
