A question for Mr Snyder, and others who believe in the chemtrail myth. Scientifically, I can explain why, on certain days when upper tropospheric conditions are right, contrails form, and then spread out, sometimes covering the sky in a dense veil of white cloud. Without getting technical, it's just a natural process that involves ice cloud (cirrus) produced by aircraft 'seeding' the atmosphere and causing further ice cloud growth which slowly advects and spreads downstream. It's not creating something out of nothing, but rather a process that causes the existing high, cold water vapour content to, through the process of deposition, cause more and more ice crystals to form.
But, if I assume for one brief moment that chemtrails are real, how do you, the chemtrail believers, account for the multiplication and spreading of the chemical elements that are being sprayed, to expand across the sky and eventually cover it. I ask this, because I've seen an example where a single trail spread out to cover almost the entire sky, and there's no doubt in my mind that the sum total of 'cloud' cover at the end of the event was 10's of times greater than the original cloud trail as laid down by the aircraft. Just curious to know how you explain this phenomena of making something out of nothing.
