Lighter than air...

This was one of those beautiful spring like days.
About 72 F high. I turned the heat on about sundown as it was starting
to chill a bit.

Ok, I thought, here is a chance to observe and maybe learn how the lift
fairies work (feathers, we don' need no stinkin' feathers!)

My little floating friend got real excited. Actually went right up and
kissed one of the air vents in the ceiling! (Hey, I didn't know he was
THAT kind of blimp!)

Within a couple of minutes he settled down on the floor over in one
corner, and - went to sleep, I think. Hasn't moved an inch since then.

That first reaction was so strange though.
Temperature? Or was it pressure?
Or was it air flow past one side?

Air is sure strange stuff...
