Lucky Duck Punch

1 package berry blue flavored unsweetened Kool-Aid Mix (Hawaiian Punch Blue works too)
1 (2 liter) Sprite or 7-Up
1 (64 oz) white cranberry juice or white grape juice
1 cup sugar (or to taste...I used about 3/4 cup)
8 scoops vanilla ice cream
1-3 new (washed) rubber duckies

In a large punch bowl, stir together Kool-Aid, Sprite, and juice. Taste and stir in sugar to your liking. Float scoops of ice cream on top. The ice cream melts and turns the punch a baby blue color with white "clouds" on top. Place rubber duckies or a toy boat on top to float around.
