Hi there,

Quite some years now, you can find in the shops a kind of plastic
globe in which one central electrode is present. If the thing is
switched on (working on batteries) plasma "plumes" are visible and these
can be attracted to one side if the globe is touched from the outside.

How does this work? Is the globe under vacuum and which gas is used?
Is that an RF source in the center?

Many thanks

Wilmert
