Laptop battery fire demonstration

A video showing the effects of a laptop battery exploding - After watching this I'm not sure I ever want to use a laptop again! What makes me laugh is the comment "if this happens move away from the laptop" - I think that if smoke starts pouring out of a laptop it wouldn't be on MY lap for much longer. The speed, temperature and explosion of the subsequent battery cells is pretty scary (but needs to be seen, especially by people who don't want to send their laptop battery back after it has been recalled.)
