"Spider lightning": It's a thing.

An especially hard weather phenomenon to catch on film but one savvy videographer managed to capture it illuminating the sky in South Australia.

During an electrical storm illuminating the seaside suburb of Glenelg outside of Adelaide, local man Caleb Travis shot the stunning lightning on Monday night.

What's spider lightning? It occurs when lightning bolts branch out and creep along the underside of stratiform clouds.

Seriously, if there's an indication wizards are battling in our atmosphere, this could be it.
