Or this video, which came out before Veritasium's

Or this presentation which came out way long ago.

This is worth the (re)watch every time it comes up.

I thought this video was a lot better than the Veritasium video. The Veritasium video was awkward. I think they tried to follow the formula from the (excellent) blue led video that performed so well, but it just didn't work.
