when I was in grade 5 me and a friend were playing with lighters. we took the metal nozzle of them and then made it so like all the gas came out at once like a 3 foot flame. Wasnt working though so I looked at it too see what was wrong and the huge flame went all over the leaft side of my head. My whole left side was singed so I walked really fast into the house and had a hower and washed the burnt hair away and did some trimming and stuff and my mom didnt even find out lol
