Creating Plasma

In this video we see noble gasses He, Ne Ar, Kr, Xe also H and N inside tubes under pressure. When we get close a Tesla coil, the electromagnetic field that the coil creates , makes the gasses react giving light.
The same thing happens every day in ionosphere.
The dome works like the tube that holds all these gasses under pressure on layers.
The sun is a pilot electromagnetic mooving source, that has an electromagnetic field arround like the Tesla coil.
These gasses are the gasses of ionosphere and they are on layers, every one in different layer, the heavier gassesgo down and the lighter up.
A moving light umbrella is the daylight, called plasma!
We can see every color from the ionized gasses on the sky.
Every blue from ionized Ar, Kr, H is the blue color of the sky.
Every yellow - orange from ionized Ne is the color before sunrise or after sunset.. (Neon reacts from long distance with the less electromagnetic energy)
