Soft drink

Don’t throw away those last drops of fizzy drink! Pour about 1/4 cup into the water in a vase full of cut flowers. The sugar in the soft drink will make the blossoms last longer. Note: If you have a clear vase and want the water to remain clear, use a clear soft drink, like Sprite or 7-Up.
