This is cooking rice the old-fashioned way. Smile and giggle included.
The pole is used to stir up the fire. You blow air from your mouth into the pole. You can always use the fan if you hate blowing some "life" into the fire but it's a bit of a trouble since the air is not directed and concentrated onto one area only unlike using the pole. Also, you're sure to get some free face powder from the ashes, not to mention a stiffing arm. So it's better to use the pole.
