Just had a near miss with some serious burns to my face.
About 30 minutes ago, i took 2 LI-ION batterys out of my torch, as it was very dim, and put them back in (as if thats gonna help).
I was holding the torch about face level in front of me, as i was slumped down in my chair.In the process of screwing on the end cap/button, one of the batteries decides it wants to be a rocket.
Flames shot out of the torch like you see on a flare, and the battery landed on the other side of my bedroom, behind me. It had to of either went straight up and down, or flew past my head.
Luckily the flames didnt come out in my direction, or i would of had some serious burns i think.
Jumped up from chair anyway, and the battery was sitting burning and smoking on the floor, and there was an extremly bad smell getting up. I grabbed my bowl of cereal from earlier in the morning, which still had some milk and honeyoats in it luckily,and tossed that on the battery

Whatever the gas was had me coughing quite bad, and gave me a bit of a sore stomach, got the window open quick though.
All in all, i was quite lucky. All ive ended up with is a bit of a burnt carpet and a unnatural fear of batteries

Sorta trumps what i was gonna post earlier about a broken ankle though.
