Plasma balls have had their day, but today they are coming back stronger than ever due to the fact that there are USB versions available. The cool USB Plasma Ball will give your desk the excitement you need to get through a grueling day of work or at least spark the interest of our co-workers. If you work at home without others around you can still enjoy the unique plasma ball and give your mind a break.
The way this works is that there are gases trapped inside the plastic sphere at low pressures. Another current at high voltages are pushed into the plastic sphere by way of an electrode found in the center of the sphere. The energy that is created causes the electrons to be stripped or separated from the gasses, which makes the plasma. Oh, to get geeky when the electrons are separated from the gasses it leaves “positively charged ions and spectacular gaseous and electrically conductive environment”. The high voltage now arc’s up through this plasma toward the lower voltage end of the sphere. The arcs are hotter than their environment, thus the glow. If you want to see, the arcs move around touch the sphere. Your touch is causing a lower voltage from the electrode thus the arc will quickly move to your hand.
What do you need to cause all this to happen? Well, you will need the Plasma Ball, a USB cable, and of course your computer with a USB port. The USB Plasma Ball is only about 6 inches tall so it will never be in your way but will provide you with some exciting color to your otherwise dull workday.
