1 oz of blue curacao liqueur
1 can of mountain dew citrus soda (or orange soda)
1 oz of 99 bananas banana schnapps (or banana schnapps)
Pour mountain dew and banana liqueur into a glass, and stir. Slowly add the blue curacao so it takes on a type of swirling effect due to the bubbles; as fun to look at as it is tasty to drink.
