I saw this idea on a website a while back and it's so easy, why not give it a try? My kids loved it and it's very easy. You just take green (lime) sherbert and place a dip or two in a cup (clear plastic cups work best because you can see the color through it). Then top with Sprite or any lemon-lime soda. For an extra touch of green, use a green straw. These make great kids companions when adults are drinking green beer!
