How hard is it to put on a show like this? Creating a plasma is definitely no problem (for instance every fluorescent light contains a plasma). Does anyone know how hard it is to create balls of light and flashes etc? I would have thought that this is the normal mode when you pump energy into a gas and that what is hard is for the plasma to be even and stable.
I did not mean to say it would be hard, or something normal fluorescent lights could not do, or that it makes the demo any more legitimate...just that he is setting up to put on a show for us. So the demo should be a little more exciting than what PhysicsforDummies is expecting. And he said we would be impressed, so let us see what he has in store.
