HOWTO: glowing balloons that show air quality

I am posting this in the UFO area bacause this is a new technology that can easily be mistaken for orbs, or nightime (maybe even daytime) UFO's. So it s really just a precautionary measure. I don't know how long these have been in use but it is just good to keep in mind. I am not saying all UFO's are these balloons, or that UFO s are all explainable. Again, just a kind of head s up.

Whoops forgot the actual link:
