Yet another "science/learning/how-to" video that talks down to its audience.
Telling people to go back to kindergarten, and mocking them for being unable to test a theory, is not going to improve the outlook of anyone, and will only piss-off those you should probably be trying to reach out to.

I think Maddox would also agree. It seems like it's kinda his thing. I see his shtick as comedy more than trying to enlighten. Also i'm guessing he's in it for the paycheck, not for changing hearts and minds.

To be fair I can't test the hypothesis that contrails are H2O either.

And then for headaches = wifi etc I think some people don't understand why their experience isn't sufficient evidence, or rather what constitutes an experiment.

We have high school students sending cameras into space. Testing the air at 30k would cost < $500/balloon. If all of the chemtrail theorists put in $100, they could EASILY afford to acquire the 'proof' they needed.
1) Decide what chemicals you want to test for
2) Select a way to test for those chemicals in the air. (active vs passive?)
3) When "Chemtrail" spotted, send up 50+ Weather Balloons in vicinity w/ chemical tester across range... 1 per half mile = 25 mile spread. (it takes 30 mins to climb to 30k feet)
4) Retrieve devices.
5) If no chemicals were found, either:
A) Dispersal of the chemical via chemtrail is terribly inefficient, absolutely no reason to worry
B) No chemicals were found

OR... and here is the brilliant part. Monitor chemicals on the ground. If they are in high enough concentration to have an effect on the human body, they'll be high enough to detect on the ground.

Testing that contrails are nothing but H20 would require a high-altitude drone or just charter a flight. It isn't that difficult to test, but the chemtrails theorists wouldn't trust a non-chemtrails theorist (otherwise they'd be over it for now).

Now someone make a video to teach Maddox what Occam's Razor really is.

Wow.. this guys a condescending asshole isn't he.

I know, and I think we've had this same discussion before. I just can't help but point it out when I see it, because that's the only meaningful contribution I can really make to the problem (because I certainly don't have time/talent to make a video of my own).
