There isn't a day in western life that goes by without something from GE's massive engineering activities making life easier for us all. So when I saw this video about their experiment to preserve a snowball in hell, I just had to see it. You should too. Although it's a bit serious for the subject, the video is a great example of today's engineering capabilities in a fun way that we can all see for ourselves. Taking a snowball and submerging it (protected of course) in molten metal is a fun way to see how far technology has come.
So the standard disclaimer: Do not try this at home. But of course, if you have the ability to achieve 2000 degree molten metal in your home, I'm pretty sure you can safely handle this experiment.
