How To Kill Lice

When I was a small child I used to have lice in my hair which I inherited from my playmates who had lice of their own heads, too. My grandma killed my lice by conducting a "lice killing session." She applied cooking gas in my head, combed my hair with a "sulod" a kind of comb made to sweep lice off the hair. She rolled a 200 liter beverage bottle on a white paper with all the lice in it to kill the lice. After the "session" my grandma would shampoo my hair thoroughly. In a couple of days, all my lice were gone.
