From Popular Science via IO9 comes a video that is very interesting to watch. I had heard of being able to dip your hand in liquid nitrogen and be protected by the evaporation around your hand for a few moments. This is the first time I have actually seen it done. Still wouldn't do it though!
Also at the IO9 link are some links to sites that describes the effect that protects the person's hand called the Leidenfrost Effect. Check out the video and the science link in the IO9 article, I didn't even know the effect had a name! huh!
