I’ve been trying to find a good, preferably animated, way of explaining the nuclear power station situation in Japan to kids (and I guess a few adults!) Wikipedia has some good stuff but it’s a very high level.
But now I just found this (click here if you are on email and can’t see it) thanks to the Wall Street Journal. Speaking as someone who studied nuclear physics for four years I must say it is a very accurate and an excellent analogy, even if polite company might not like it too much!
View it yourself and then please show it to your kids.
