Crazy Chinese Popcorn Maker

The video doesn't give this much justice, so I'll give you a little description as well.  The machine that the guy is turning is full of popcorn kernels.  The kernels are sealed in that thing he's spinning around.  As they heat up they don't explode, because they're sealed with no air going in or out.  He heats them up to a certain temperature (or in his case for a certain amount of time) and then he puts the sealed container with hot kernels into a bag.  He then opens the container in the bag, allowing the kernels to expand, and every single kernel pops at the same time in a massive explosion.  This is so cool.
