Exploding laptop batteries

Laptop batteries have been exploding for a long time, but it’s been a phenomenon I’d largely ignored until now when I read an Inquirer article about a MacBook exploding this morning. Then I went in search of evidence. I found this video= and I realized that when they say exploding, they actually do mean exploding.

According to an article on the subject at Howstuffworks.com , these explosions/meltings/fires are caused by small amounts of metal floating in the lithium fluid piercing the separation walls between the cells, causing a short circuit. Bad luck eh?
