I recently watched Adam & Jamie Test Disposable Cigarette Lighters , when they put the Lighter in the Dryer they missed the point , in that normally when a lighter ends up in a dryer it is in a Shirt or Jeans pocket .
So when the Dryer Starts , the material twists around the lighter releasing the gas into the dryer , the Centrifical Switch in the Electric Motor Provide The Spark to Ignight the gas .
My Dryer Changes Direction about every minute .
