It exploded in my hand!

Moments ago I was writing about an amazing coincidence with my car that happened the other day, when all of a sudden my mouse blew up. Actually a battery inside my mouse blew up and made a loud fizzing noise as white juice leaked out of it. It was really weird and I didn't know if the stuff was toxic. Some got on my hand, but it doesn't burn. Here's a boring picture. Car story to come tomorrow.
