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.

There are a lot of times when we can just time something and say "busted" or "confirmed" or whatever, instead of building a robot or some gadget to make it happen more elaborately. In those cases, we're simply enjoying ourselves.

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.

From our point of view, we're just curious, we're poking around and having fun. If it's science, if it's accurate, if it's not accurate, we did the best we can to keep things clean and understandable, but we're just having fun, so sue us if we got something wrong.

I've learned that I can pretty much do anything I've wanted to as long as I was methodical and diligent about it. It may not sound very exciting really, but it works.

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.

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.
