Science lesson

Well, vacation is over and I’m back at work.  Today’s blip is an image of my hand on a plasma ball.   It's a 30 inch ( about 76cm) glass ball filled with argon and neon gases.  The center electrode is at a high oscillating voltage.  The electrode throws off electrons which travel and interact with the positive ions of the gas, which creates “plasma.”  I won’t go into any more science.  It’s on the internet…


I work in energy efficiency and we use the ball as part of an educational program with customers and students.  It’s always fun and a little cool to play with.
