LOL. I figured the guys in the video were trolling; you can hear it in their voices.
Thanks, I tried to find more about it, but I was unsuccessful. That contrailscience site (I think it is yours?) has answered MANY questions.
Someone I know is considering building a "chem buster", and I'm trying to get him to define exactly what "successfully destroying a chemtrail" will look like. There seem to be lots of excuses available when they don't work: they're miscalibrated, they're poorly designed, they're full of orgones, the chem trail people are targeting the device, etc. Yet no one (or at least no non-psychics) seem to know why they work when they do "work".
