I mentioned a fun weekend project called Smashfest 2011 in my last blog entry. Liquid nitrogen provided quite a bit of amusement by allowing us to smash objects that wouldn't normally smash. Like a marshmallow. I also asked for your videos last week and my lead sent me a video that is simply amazing. Check out how liquid nitrogen can expose the magic of quantum physics. Mind blowing.
Wondering how it works? It's explained here.
