Plasma Ball Detail at CosmoCaixa Science Museum, Barcelona

This is a detail of a plasma ball at CosmoCaixa Science Museum. Many of you have seen these balls that seem like octopuses or aliens extending their tentacles whenever someone dares to touch the surface of the crystal sphere. It was hard to take this picture since I had to avoid the use of flash on the reflecting surface and I had no tripod with me at the moment to gain stability and look for more natural light in the dark pavilion. I hope you like the result. The tiny star-like spots are just reflections on the ball that I did not edit to keep the cosmic look of the image.

Now to enrich our scientific knowledge a little bit, a definition of
