How to Get a Plasma?

If it's not hot enough to make plasma, there's a whole variety of chemical reactions that can give off this kind of light. For example, either you could be like pulling water molecules apart and smashing them back together. And when that happens, that's actually called fracto luminescence. This is a commonly known effect in solid state physics,. When you're pulling apart and then reuniting things with charges, they can give off basically static electricity, little sparks. The trick is, how do you get a plasma? In order for that to happen, you need more than just compression. What you need is like a super sonic shock wave. You need this bubble to collapse faster than
