Strange Video of Dancing Cloud Explained By Electric Discharge

The Bad Astronomer writes "A few months ago I was sent a really weird video showing a cloud snapping around suddenly, far faster than wind could explain. I asked a meteorologist about it, who told me it was due to ice crystals re-aligning when the cloud's electric field discharged. It's pretty amazing to watch, and a great example of how many cool things happen right in front of us that we never notice."

And since they won't be able to do it, the conclusion will be "busted" (even though it is actually possible).

I love the show, but when they conclude stuff because they can or can't do something it kind of pisses me off :(

Reflection

[Tony Isaac]

It doesn't look like part of the cloud to me, the brightness and tint isn't quite right. It looks more like a reflection, as if there were glass between the camera and the sky, with something in the foreground reflecting at just the right place to make it look like part of the cloud.
