My Fingertips are Melting!

So what exactly is that picture above?

That's what happens when twenty-year-old polyurethane fingertips break down. Gooey mush.

My advisor had this robot hand in his garage for a long period of time and then moved it into his office. After that, I guess, the PU really started dripping. BTW, if you don't know it, polyurethane is what skateboard wheels and many foams are made out of.


On the photographic side, these images were a nightmare when it comes to color balance. I just couldn't seem to get it right. Too bad I didn't have my gray card as a reference -- I lost it about six months ago but I know it is somewhere around my house or office.
