Very cool! I just sent it to my wife, the chemistry teacher.
Major props to JT for the sig.
at first I felt like I was watching him make like heroin or meth or something
Yeah, that's cool.. Another thing I found cool (though I don't have any video of it) is seeing an explosive device (any type, except I guess something like a nuclear bomb) explode when it's first cooled to VERY low temperatures.
It still explodes, but happens in real slow motion, and the explosion is more like a soft puff than anything else. Sorry, don't have any videos, but a friend from physics once showed me that.
That is very cool.
