Why does peeling adhesive tape (or scratching certain crystals) sometimes give off flashes of light, and can it really generate X-rays?

Post a problemWhat is the physical mechanism that produces ball lightning — the luminous, floating, sometimes room-sized spheres of light occasionally reported during thunderstorms — and can it be reliably reproduced in the lab?
Ball lightning
Research level
What physical mechanism, if any, produces the glowing floating spheres of light during thunderstorms reported as 'ball lightning'?
What is the highest magnetic field you can generate by exploding a current-carrying wire?
Research level
If you send a large enough electrical current pulse through a thin wire to make it vaporize, what is the maximum magnetic field achievable near the wire before it disintegrates, and what ultimately limits the field strength reachable this way?
What is ball lightning, physically?
Research level
What causes ball lightning -- the rare glowing, floating orbs of light, sometimes seen after ordinary lightning strikes, that can persist for seconds and even pass through windows or walls?
