Fun for us just happens to be screwing around with anything that gets our attention and is thought-provoking.

We're constantly pushing these materials and processes to the extreme to see what will happen. It's an insight into things that you don't normally see.

Dealing with effects, as a job it's great, but with Mythbusters, the stuff we've seen, the stuff we've absorbed over the years, has just been fantastic, and I wouldn't change it for the world.

I have to say for both of us [ with Adam Savage], this experience that we've been having here has changed us dramatically, and we've evolved since we've come on the scene with Mythbusters, because of what we've learned, and that, I think, is the biggest reward for us.

All of the experiments are really cool. Probably one of the better ones is "Running in the Rain." It depends on circumstances: how fast are you running, if there's wind, or any of the other things involved with the circumstances of running in the rain. That's a favorite, I suppose.

The idea that you can contribute is really important, especially for a kid.

One of the things I'm likely to start building in my shop is a vehicle wherein each wheel has basically a flight-simulator base as its suspension. It's known as a hexapod; it's basically a tripod but each leg is two pistons. So you have six axes of freedom on it. This will be something that can not only do what lowriders do, but shorten or extend its wheelbase and jump forwards, backwards, or from one side to the other. In an off-road situation it could be rolling at speed toward a ravine and then leap across it.
