Rent an airplane with sampling equipment and fly it into your so-called "Chemtrails" to collect data. Now have that collected material analyzed by a licensed chemical laboratory.

Don't try to claim that you cannot afford this. There are THOUSANDS of "Chemtrail" nutcases out there. Have them contribute ten dollars each and you can easily pay for the project.

You will NEVER do this because you know as well as I do that "Chemtrails" are BUNKUM.
