If you asked us to explain how a nuclear reaction works, chances are we'd throw our hands up in the air and change the subject to that funny video of a begging cat instead.
Realising this, some clever chaps at St. Mary's University in Halifax have put together a nifty vid to explain it all in easy-to-understand and, more importantly, really fun to watch fashion.
As workers at the Fukushima Daiichi power plant bravely battle to prevent the reignition of nuclear chain reactions in damaged reactors, it's useful to know exactly what this means.
This video utilises plastic golf balls and mousetraps to simulate what a chain reaction actually looks like. Take a gander for an explanation and also to see loads of mousetraps go off.
