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.

Congratulations on the new show! Did having a kid make you want to do another show specifically for kids?
No, actually we've been talking about this for a long time. Ever since 'MythBusters' started, teachers, parents and kids come up to us and say that we're the reason they're interested in science. It's just become such an amazing platform to be able to inspire that really key age, that middle school age, where kids start to lose interest in science. It was just a really nice side-effect. And this is an amazing evolution -- we're taking 'MythBusters,' taking all the commercials out and then adding even more science. And it's right after school when kids come home, so hopefully we'll be able to capture them.

The fact that it's you hosting can only help -- people love you from 'MythBusters'!
I hope that they identify with me. I don't have a background in science. I am just authentically excited about the topics we're talking about and hopefully they can learn with me and get excited with me. I'm reading about all the things I'm telling them about, and I'm loving it.

This is for middle schoolers, but do you think kids of all ages can tune in and enjoy?
Oh of course, I hope so. Generally if you've got middle school, then you've got the younger ones because there's a lot more sophistication in kids than we ever give them credit for. I'm sure that the younger audience will look at it, and hopefully we'll get the older audience too!

Is there a plan to take 'Head Rush' into the classrooms?
Well you can be interactive with it online -- you can make teams and as a classroom and you will have the ability to compete against other schools. And, since it is commercial-free, we're making it so a teacher could very easily record it and bring it into their classroom. It's unlimited where it could end up. You'll be able to be online with the show, while it's going on, asking questions ... it's pretty amazing.
How difficult is it juggling motherhood and now two shows?
It's all about not being able to waste any time. I've pretty much got everything scheduled. It's working out -- I've got a huge support team with my parents, my family and my husband is amazing. It's all about a lot of family support and a lot of to-the-second scheduling. [Laughs]

When you were a kid, what were you really into?
For me, I've always been sort of an arty geek. Like on Halloween, I would make our entire yard into these amazing sculptures with Cheerio boxes and tin foil. I was really, really into special effects. I wanted to grow up and be a special effects artist. It just turned out that once I got to that age, the industry I wanted to get into was sort of becoming outdated. So 'MythBusters' was an amazing avenue where I could still incorporate art into the field, and there are a lot of special effects artists around me. I'm so happy I've ended up here.
