Good thinking Paul. I'll buy that explanation unless someone comes
up with a better one. The flame bubble is relatively diamagnetic compared
to the surrounding air.

If I try this with a non-turbulent argon stream (or N2 or O2 stream), what
would be a good marker substance? Break open a july 4th smoke bomb? I
bet that stuff doesn't need O2.

Hmmm. What about a stream of extremely hot air from a nichrome wire?
The density might be low enough to make a difference. This gives me an
excuse to try the Schelerein trick with a superbright LED, telescope
mirror, and a little video camera.
