You can play music on it. No, seriously. Check out this plasma tweeter:
This is a prototype of a FM modulated plasma arc speaker / tweeter. Currently in the process of making an improved vertical discharge setup, using tungsten-tipped electrodes. Hopefully, this will stop the plasma hopping about & causing unwanted distortion…
That purple plasma spark you see there is about 60,000 volts.

is the song we’re hearing coming from the plasma itself? (ie producing sound waves??)

Yup.
I find that adorable, tiny dancing purple music… lovely

You lost me at modulated. But I like anything that plays music, so bring on the plasma I say.
“FM modulated plasma arc speaker / tweeter”
“improved vertical discharge setup”
Must be some kind of secret geek speak.

If it helps, I have no idea what he’s talking about, either. Ooooh! Purty!
