A recent article I got from a "believer" friend claimed that meteoric dust within a crop circle "prooves" that it can't be a hoax. (no where in this "scientific" article did the author show that he sampled soil away from the crop circle as a control group). I'd like to use this example to educate him about scientific methods vs. psuedo-sci methods.
