'Blues Clues' has been incredibly good to me, and I've been working so hard on it for so long that I take it very personally. I wouldn't want to do anything to jeopardize what so many kids love. So there's a lot of responsibility there.

There are a few elements - especially platinum and palladium - that have the amazing ability to absorb up to 900 times their own volume in hydrogen gas. To get a sense of the scale there, that's roughly equivalent to a 250-pound man swallowing something the size of a dozen African bull elephants and not gaining an inch on his waistline.
