I remember the story of a pilot for Civil Air Transport in China. He
was flying some VIPs around on a tour, and at the end they thanked
him, with the most Important of the VIPs saying: "We knew you were a
good pilot because every morning you tasted the gasoline!"
What he was doing was taking a sample from each tank in the palm of
his hand and bringing it close to his mouth to blow on it, thus
evaporating the gas. (If it had been water, it wouldn't have
evaporated.) So it does have a pretty good evaporation rate
(To be sure, that wasn't 100LL. It was "high octane" for the time,
which was probably also 100. Or possibly, since this was a C-47 or
C-46, and the country was China, it was 80 octane.)
