Testing out the underwater plasmaphone for ICMC 2007 concert

[AKAtheA]

How well can it electrocute the operator? :D

How do one of these things actually make a pitched note?

[naaaaaagz]

@19andoverlol guess it depends on the bars' length (the huge thing hanging from above)

What Exactly Is An Underwater Plasmaphone?

[hydraulist]

It's a plasmaphone in which sound is generated by matter in its fourth state (plasma) but the surrounding medium is water. That's what the trays of water are for; here each note has its own tray of water. The hydraulophone obviously works underwater too, so its surrounding medium can be water or air, but in either case the sound comes from matter in its second state (water). This just shows that the surrounding medium is a second variable in addition to the sound-production medium.
