So what do you think? A few hundred years of burning fossil fuels into the atmosphere isn’t going to make aluminum concentration even higher than it’s supposed to be? no matter where you test? Hhmmmm… Do you mean to tell me that if I want to do a “chemtrail” test that my data is completely messed up because Aluminum exists everywhere in abundance? That’s right… Testing for Aluminum is not proof of chemtrails… There goes a few hundred videos debunked… While we are on the subject of testing… Lets go for Barium.

A coal plant may produce 1.4million pounds of Barium every single year, even though there is a push for decommissioning in 2012 there are still 572 coal plants in operation in the US ALONE… that’s about 800 million pounds of Barium from coal plants per year in the US ALONE… Barium is not an indication of chemtrails, Barium has been a pollutant since the industrial revolution…

A commonly used meme in the chemtrail theory are the photos of barrels on aircraft. These are used in testing to see how the aircraft performs under different weight loads. pumping water into different barrels to imitate a higher weightload at the rear/front, sides etc.  - http://metabunk.org/threads/661-Debunked-Chemtrail-Plane-Interior-(...

Another Common misconception is that Contrails are only caused by Jet exhaust, and didnt occur until recently.
