More fun video from those folks at Jlab! This time, based on someone's suggestion, they froze an egg.
Unfortunately, there aren't a lot of physics discussion in the video itself. If you go to the YouTube site for this video, you get a bit more of some of the physics surrounding this demonstration in the discussion and comments. The one thing they asked was why it took 8 minutes to freeze the egg, but it took 2 hours to thaw it, even when the temperature change is the same. This is a good question to ask the kids! :)
