Yup, I have gotten the united Nuclear ones. Blue green and aqua.
They work pretty good, although when they said the glow lasts for 12 hours I was expecting more, it will glow really bright for a minuet or two after being exposed then basically go pretty dull. But they really do last that long.
I haven't yet mixed it with anything, but they are fun to light up inside their bottles. The blue one looks like some weird chemical science experiment when you light it up. ;D Its pretty neat to put in some water and shake it up after exposing, it's like a glowing blue Gatorade. (although the stuff settles to the bottom pretty quickly). Green is the brightest by a long shot (obviously). But I think the blue looks the best and most exotic.
