once when I was a child I threw a bottle of alcohol on a barbecue (at that time alcohol was the ones that caught fire very easily, not like those nowadays that have more water than alcohol) And obviously the alcohol caught fire very quickly, got into the bottle and exploded in my arm. I started running with my arm on fire screaming desperately for about 40 seconds until my aunt showed up with a towel and put out the fire, but I had already burned badly, my arm was very red, swollen and painful for weeks, but by some miracle I didn't have any scars.
