### Kinetic Karnival now on YouTube

Here's a post from 2009. Updated as I've added the videos to my YouTube channel. I downloaded them from Jearl Walker's MySpace page, where they were originally posted.

All six 30-minute episodes of Jearl Walker's classic television series, the Emmy-winning Kinetic Karnival, are available online at Walker's MySpace page. [Update: I can't access them on MySpace anymore, even in Chrome.] I recommend watching them before showing them in class, although I'm sure you'd do that anyway. There are a few brief moments that modern educators might find objectionable. Most of us find ways to work around such moments, but it's always best to be aware.

I developed video question sets for episodes 1, 2, 3, and 5. Students answer them while the video is in progress. They're up as PDFs in The Book of Phyz.

Here's a one-stop collection of Kinetic Karnival links for your convenience. If you like question sets matched to science videos, The Lessons of Phyz is the place for you.

1. Forces and Collisions [impact time and contact area]
In this episode, Jearl proves his virility and masculinity by chopping concrete bricks with his bare hands and volunteering as the meat for a “nail sandwich.”

2. Rotation [circular motion and conservation of angular momentum]
I show this one in two distinct segments (one in my Physics 1 course, the other in AP Physics 2). The first third is devoted to circular motion. The second two-thirds is devoted to angular momentum. Do I dislike the blending of these distinct topics? Yes. Do I have the talent and ability to produce my own series? Not so much. In any case, this episode features Jearl in a swim suit!

3. Fluid Flow and Friction
In this episode, Jearl debunks the drain swirl myth from the bathtub, describes an early dating disaster, explains the tablecloth trick, and hangs a spoon from his nose.

4. Viscosity [non-newtonian fluids, quicksand, and corn starch]
Jearl enjoys tinkering with viscous and non-newtonian fluids. He gets stuck in quicksand and jumps feet-first into a pot of unflavored gravy.

5. The Leidenfrost Effect [heat transfer and phase change]
Arguably the best program of the series, though it does contain a "politically-incorrect/racially insensitive" moment. When Jearl complains about "the problem" with iron-cooked crepes, you might find the mute button on the remote control of your playback system. A few moments of mute will spare you an apologetic discussion afterward. Features the hand into molten lead, liquid nitrogen in the mouth, and firewalking.

6. The Science of Cooking
Jearl prepares a meal for a dinner date with a young lady. Along the way, he describes the physics and chemistry of a variety of dishes. And the date turns out as you might expect.
