If you’re a fan of “Mythbusters,” and especially if (like me) you’re a fan of Kari Byron, check to see if you get the Science Channel (a corporate sibling of Discovery Channel). Today, Kari started a new daily show called “Head Rush,” a commercial-free science show for kids which adults will enjoy too. I, personally, would watch Kari read the phone book for 30 minutes, but that’s just me.

I’m watching the first episode, which I DVRed while I was at work (the show airs at 3 p.m. Central). It contains extended clips from “Mythbusters,” interspersed with science material (think “Bill Nye, The Science Guy” or “Beakman’s World”) hosted by Kari. Grant Imihara reassured his Twitter followers today that Kari is not leaving “Mythbusters,” by the way.
