Later, the room was lit up with the usual indoor lights, though there was no daylight coming through the window. In these conditions, the tendrils were a little brighter, with a little more reddish-purple color, and more clearly defined. I switched off the overhead light and its display really stood out. There was ambient light from the adjacent living room, but the ball really looked bright and the tendrils were lit up really well. Very cool looking and 500 percent better than anything I had seen at the department stores (of course those are under those very bright flourescent store lights).Read more ›

Some of you might be thinking about purchasing a smaller one to save money, take my advice, don't. Trust me on this, once you get this 8" ball, you will be glad you did. And keep in mind you are still saving money, cause years ago these things cost between $100 to $200 dollars. You don't believe me how beautiful and cool this thing is? Just watch the video! :-)
UPDATE NOV, 19 2010
I just wanted to let you all know that my plasma ball has officially already died! I only put a total of 3-hours on it at the most. I now give this product a 1 out of 5.
The globe itself if 8" in diameter and has a central electrode inside that emits the lighted "plasma" arcs.
As far as being an educational toy, it's fantastic because it gives a pretty hands-on display of the 4th state of matter, which is plasma. You can't get a better display of plasma than this, other than looking at a neon sign or telescope pictures of neublas or solar flares.
It works by charging special inert gases and noble gases (neon, xenon or krypton) in a vacuum inside the sphere with high frequency (30,000+ hertz, household AC current is 60 hertz), high voltage (2,000+volts) DC electrical current from a transformer in the base. The electric charge comes out of the electrode and excites the gases' electrons and causes them to illuminate as plasma filaments eminating from the center electrode. The filments reach out from the source to touch the glass sphere, which acts like an insulator to block the current from coming out.
When you touch it with your hand (the body is conductive and has good resistance) the high frequency electromagnetic field (flourescent tubes also have this) around the sphere is altered and a single filament of plasma forms from the inner electrode and flows to the contact point.
Now, these are fascinating things, but the physics that makes them work also makes them a little dangerous. The high frequency electromagnetic field surrounding the sphere can cause problems with other electronic devices. It can cause electromagnetic interference, put stress on delicate electronic components, or even damage circuits.Read more ›
