Incense bottle smokers are a very unique item. They are used for aromatherapy or most often to providing a pleasant atmosphere in your home. They are very easy and fun to make. All you need is a unique bottle, a drill motor and most important a diamond drill bit (hole saw). A 3/8" diamond drill bit will work just fine...
