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

If it turns out that we're doing proper science from time to time, it just happens to be that that's the most efficient way of doing it. We go into each of these stories with an open mind, and one of the great things about how the show works is that we're not approaching it from a doctoral point of view, we're just trying to see what happens.

We may not have a sample size larger than one, or we may not have unlimited resources - it's a TV show, and we generally turn these things around in about a week or so.

I always telling people to "not try this at home," because most of what we do on MythBusters is really dangerous. Consequently, we can't encourage people to try that stuff.

We've found that the biggest thing as far as the danger is simply pressure.When we work with explosives, we've got bomb technicians there, bomb-squad guys who go into unknown situations all the time, and they've dealt with it safely.

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.

When I figured that I could do anything if I was simply methodical about it. I went to the library - and this was before the Internet - and I searched for a career that was creative, would not fall into a routine, involved problem solving and making things. It also had to be dynamic. I came up with special effects.
