Laptop Battery Exploding caught on camera.

Laptop Battery exploding whilst I was showing a client that i had reinstalled Windows for him. Notice 3 individual explosions as separate batteries exploded. I run a small laptop and computer repair shop in Rockingham Western Australia. This laptop came in for repair because a corruption of Windows that was stopping it from booting. I had it running on my bench for 3 day straight before this happened. Looking back at the Video I'm amazed I was not injured by the repeated explosions.
