Fascinating and fun. USB Plasma Ball is fascinating to watch and even more fun to play with –Placing a finger tip on the glass creates an attractive spot for the energy to flow, because the conductive human body is more easily polarized than the dielectric material around the electrode providing an alternative discharge path having less resistance. The Plasma Ball is great for kids of all ages. Whether you are a fun loving work professional or a parent who wants their kids to learn about static electricity without the need to google Tesla's high voltage plasma globe. This is a great year round gift idea. Measures 6 inches tall. Globe measures approx. 3 inches diameter. Base measures approx. 4 inches diameter.
