I think that I struggle with math, but I seem to be pretty good at estimates in my head, and I can derive engineering from high school physics. One example involved the Air [powered] Car which had about a ten year run as a successful stock fraud. I knew at a glance that the numbers in their brochure were impossible, and told an author who had praised it. He replied that so many other people couldn't be wrong, but almost all of them had gone to the same science class and then farther in school than I. All it took was one person willing to wait for its tank to run out, which actually took minutes, not hours. I wish I'd been there, taking bets. I am also very quick to detect similar tricks, like perpetual motion machines.

Reminds me of that news story that swept the nation like five years ago. About that yuppie couple in California who launched a search party for their little boy...who they said had been carried away into the sky by a big decorated party balloon.
They showed a photo (taken indoors) of the kid with the balloon, and it was huge for a party balloon, and about five times the size of the kid. But (since I had gone through an aspie special interest phase of being into Zeppilins decades earlier) I could see at a glance that the whole story was a hoax. I could see that there was no way that that balloon could lift that kid because a fifty pound kid would need almost a thousand cubic feet of helium to get off of the ground (the balloon would have to be over ten feet tall and wide), and would hafta dwarf the kid, and wouldn't even fit inside the house.
Days latter they found the kid alive and well in basement of the house.
That sounds much like the Colorado balloon hoax that happened on October 15, 2009. The balloon in that case was shaped like a silver UFO. It happened over in Boulder, many California transplants live there. The parents were charged for the expenses that were wasted on the search and had to do community service. I thought at the time that a kid could not survive inside the balloon, as there was only helium gas in there and he was not spotted outside of the balloon.
