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.

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.

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

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.

Actually I'm pretty adamant about, you know, the whole God thing and it seems that skeptics are by and large atheists or something approaching that, which I strongly identify with. So it turned out to be a good thing and I have become enthusiastically part of it.

I would love to have access to a company like Caterpillar. I would make all their stuff remote controlled and work ten times as fast.

There are a lot of things that I'd do differently. But I can't imagine being more fortunate than I have been.
