Meth Cooks May Be Caught Pink-Handed

WICHITA, Kan. Aug. 21, 2004 — It may fall a shade shy of catching thieves red-handed, but for farmers fed up with methamphetamine cooks filching their fertilizer, staining them pink will do just fine.
Assuming you can discourage thieves you cannot easily catch, a new product called GloTell which is added to tanks of anhydrous ammonia will not only besmirch the hands of those who touch the fertilizer, but leaves its mark on anyone who snorts or shoots the end product.

How freakin' awesome is this... It's like a big screw you to the cretins who steal fertilizer to get high (which in itself is patently absurd).
I'd like to nominate this for the most creative use of science award.
