Re: Parts of it date back to when fire was invented
In a similar vein, I was at school with a guy who thought it would be fun to pour petrol on a fire before lighting it, not realising that the vapour pressure of petrol is quite high and the flames therefore tend to flash back. In this case, to the empty can he was holding. He needed skin grafts from his thigh to replace the skin he no longer had on his hand.
