head rush

We know and love Kari Byron from 'MythBusters,' and now she's taking her enthusiasm and curiosity about all things science to a new after-school show aimed at middle school-aged kids.

'Head Rush' takes all the best bits of researching and testing hypotheses from 'MB' and walks its viewers through the process step by step. Encouraging kids to follow along at home or in the classroom, the show is conveniently commercial-free for totally uninterrupted experimentation.

I caught up with Kari to hear more about her new show, getting interactive with viewers, juggling both shows with having a new baby and her own unlikely path to TV science expert hall of fame.

Love 'MythBusters'? Can't get enough of Kari Byron's endearing fearlessness? Then definitely check out her new show, 'Head Rush.' Yes, the after-school science show isn't exactly made for adults, but whose physics and biology knowledge couldn't use a little brushing up?

I also preview Jackie Warner's new weight loss show 'Thintervention,' which she says is designed to target her clients' bodies, minds and souls. So which celeb does she want to help rehab? I see a spinoff, Bravo! Then I catch up with the Kids In the Hall to talk about their new murder mystery miniseries 'Death Comes to Town' ... and squishing heads.
