Lightning strikes hitting the ground can produce ball lightning.

Since then scientists have been able to recreate ball lightning in a lab, but nobody had ever been able to satisfactorily record a naturally occurring example.

Now a science team in China believe that they've achieved the impossible by recording footage of ball lightning that formed during a storm in Qinghai. Using a combination of spectrographs and video cameras, the researchers recorded the glowing orb of light as it rose 5 meters above the ground."There have been many research programs that routinely video or photograph natural and triggered lightning," said lightning specialist Martin Uman. "But none, as far as I am aware, has stumbled on a ball lightning."

The theory goes that when lightning strikes the ground it can store energy in silicon nanoparticles which then oxidize, releasing their energy in the form of a ball of pure silicon vapor.
