A first google look didn't reveal anything (didn't look past the 5th link though), but you could always try selling it to nearby neighbors... and set up some kind of booby trap that will trip them when they cross into your property. It'd be fun to see if they fall for it.
One standard physical experiment is to dissolve what you have and the boil away the water to see if you get the Terpin Hydrate crystals back.
You could probably get a stronger reaction in whatever you try with a more pure form.
