I guess that means cigarette smoke rises because it has negative wind resistance. It's very counter intuitive and hard to understand... but that's physics people!
Russ was still of this opinion just a few weeks ago. In youtube thread he was arguing that small particles have a larger "density to volume ratio" and so are heavier for their size than the same material in larger amounts.
He was confused when it was explained that density already is a mass to volume ratio and thus can't rationally be included in another ratio to volume. He eventually started to claim that his density to volume ratio claims were a typo even though he includes the same ratio concept on his webpage to justify the fast falling particulate claim.
Hopefully suggesting it was a typo indicates he has realised his original misconception and will revise his thinking somewhat.
