Incredible class with liquid nitrogen. I heard one kid say, "this is the best class I've ever had" and another said, "I wish this class would never end." I thought that they were crazy, using my bedside table light upside down, plugged in and immersed in clear liquid, with a broken light bulb and yet glowing. But it worked, no damage, and lots of amazed kids and adults to boot.
