Why are there two different colors of the plasma in the plasma ball?
- Ronell Booker
I assume that you are referring to plasma balls like ours with
both blue-ish and red-ish colors inside. This happens because the globe
actually contains two different gases - helium (which glows blue) and
neon (which glows orange-red). The combination of the gases causes the
effect that you see.
An interesting thing that happened to us recently is that our
plasma ball was damaged in a way that caused all of the helium to leak
out. Now it only contains neon, and we only see the orange-red color.
(I will try to add a picture of this if I can get a good one.)
