A man recorded an EF-4 tornado that touched down in Bonner Springs, Kansas, using a GoPro clamped to a metal fence post up until the storm ripped it out and blew it away.

The incredible video, filmed on May 28, shows how in the span of just under five minutes a sunny day became a whirling maelstrom, as the tornado advanced closer until it eventually pulled out the fence post that the camera was affixed to.
