Lightning researcher Tom Warner went on a storm-chasing expedition with his daughter this month - and brought back some stunning slow-motion video of lightning making its way to earth.
The footage was recorded at a whopping 2000 frames per second. To put that in context, cinema is usually run at 24fps, while modern gaming usually runs at 60fps. What you're watching is slowed down about 80 times.
"My daughter got some nice high-speed camera captures of lightning while I drove," Warner writes in the video description.
He said the pair chased "a small storm system" from Rapid City, South Dakota, on the evening of July 12.
Video like this requires some specialised equipment - in this case, a Vision Research Miro 4 camera, a professional-level solution worth thousands.
