Need to add some spooky ambiance fog to your super-scary Halloween party? Rather than shelling out money for a fog machine you’ll probably only use once a year, simply make a trip to the nearest drug store and pick up a bottle of glycerin, a gallon of distilled water, a 2-liter bottle of coke, a disposable mini-pie tin, and a big candle in a jar.
Mix together one part glycerin and three parts water to make your fog juice. After that, set up a stand so that the big candle heats up the bottom of a pie tin with the top half of an empty soda bottle taped over the pie tin opening. Add a teaspoon of fog juice into the tin heated by the candle flames and enjoy the spooky fog effect.
