John,
You too never cease to impress by providing bits of knowledege I've 
never heard about.
Leidenfrost effect. My first instinct was to dismember the German word, 
which was a bad idea. Wiki told me about the relevant meaning.

Yes, that is a possibility about what I may have observed.

Let's see. I should produce the same efffect by jamming the hot end into 
a tight insulating hole. Shouldn't be too hard to test subjectively.
My guess --  there is more than that involved. But just speculation so 
far. I haven't even proved my initial observation.
