Watch the flames turn into beautiful rainbow colours.
Fill a bucket with dried pine cones. Make a mixture of 3 cups of epsom salts to 16 cups water. Pour over the pine cones then let it soak for several hours. After soaking, place the cones on a cookie sheet or somewhere flat to air dry. Once dried, throw a few into the fire and watch the flames turn into beautiful rainbow colours. A real nice treat to see!
