Hi all.
Seems that I may have stumbled across something new.
Recall that hot air balloons rise, and argon-filled glass spheres light up when placed in an RF field (see numerous Youtube examples)
Now what happens when you blow bubbles filled with argon and place them in an RF field?
Hint:- they glow and go up. At least until the bubbles burst.
I have in mind something like a large hemispherical sheet (perhaps clingfilm or similar) where the newly generated bubbles sit, within the RF field of a small Tesla coil.
the bubbles themselves could be generated by supercooling bubble fluid in a domestic freezer (this increases the viscosity) and adding argon gas from a suitable cylinder.
then the (cold) container with nozzle is gently heated to blow bubbles automatically.
reckon this has any hope of working? it would seem that due to the Leidenfrost effect each bubble may last tens of seconds due to the intense heat evaporating water from the inside of the bubble so quickly that it forms a steam layer and stabilises the bubble for a while at least.
the limiting factors here would seem to be longevity of the bubbles and the lift generated at a given RF field strength before too may destabilise.
Maybe Tesla's vacuum pump was actually a part of his work as most of the remaining gas in the chamber would be argon. I wonder.....
