This mcintosh apple scented gel is for use in our electric glow bowl unit. Using this glow bowl gel is a great way to freshen up your home and create an amazing looking colored light with out using an open flame. To use it, pour about half the bottle into the electric unit and turn it on. A low watt light bulb below the glass cylinder will warm up the gel which releases the fragrance into the air. In about a week you may start to notice that the gel has started to look dried out. At this point you can add a little water to the gel to refresh it. When you do not notice the fragrance anymore you can dispose of it or put it back into the bottle and change to a different fragrance.
