Spontaneously Exploding Beer?!

A very peculiar event took place the other day. I was in the living room reading, when all of a sudden, I heard this loud crash followed by a shrill scream. I got up and ran into the room I heard the noise coming from. What do I find? Broken glass and beer everywhere. Apparently, a 40 just exploded... spontaneously... wtf?!?!

A girl that was on the other side of the room got hit with a piece of glass and was bleeding. Some of the glass was embedded in the wall because of the power of the blast. One girl's computer and cell phone were ruined (ouch) from all the beer.

I am still in shock over this. Has anyone ever heard of this happening before? I googled it, but not much came up. I'll show you what did come up though:

I'm very upset I didn't actually get to see it explode. It must have been so cool. Oh well.

Peace,

Kim
