For less than $20 you can demonstrate the corona discharge of high frequency current going to ground on your desk. This little guy does the job remarkably well with good energy and illumination for just running on (2) AA batteries. Let's hope the electronics last longer than I'm expecting at the reasonable price.

Always a crowd pleaser.

This is just about as perfect a gift for my kid as they come (but I'll be playing with it too) Wish i could give it 5 stars but it I can't cause I really wish they would include a power adapter, I would have no problem paying extra for it.

This is fascinating and works perfecty. A little harder to see in a bright room, but is still great!

Nifty little ball of lightnin'. Not super bright but that's ok considering it's so small. It does work with AA batteries but they don't last long. Best to figure out what kind of AC adapter will work.

My hubby enjoys it, but he also enjoys playing with it with our two-year old twins.
