First, Clifford Johnson helped make the very cool video Shine a Light, teaching kids about how atoms emit light. Now he's done it again with Laser. [Click the "HD" button to see it in better resolution.] It's pretty good. I like the way the actors work, and how they're dressed. I'd like to have seen more about why laser light is all one energy, and how it gets collimated, but sometimes you can't put everything you want in a short video without making it murky. Still, there's a lot of good basic stuff there. I think this will do well in the classroom, so any physics teachers out there, take a look!
