Denise is one of the leading dolphin researchers in the world and has been pioneering work on dolphin communication, most recently with her CHAT system. I had been following Denise's work for years, and I was…

not a whole lot. The part is porous enough that water forces its way in, eliminating any air pockets, and filling the structure. The part on the left, which was exposed, is even smoother then it's companion (they were smoothed in acetone vapor together.)
