Well then the "HomeScientist" in Seattle would be on no-fly for sure 
for his YouTube HomeScience videos.  I love watching this guy's

He'd fit right in on this board.  LOL.

It's remarkable how many chemists I meet who say they got first

thought they could learn enough to build their own guitar amp.
