I have made this punch for several baby showers and it went over really GREAT. It seems to be the most simple way to make a very tasty and beautiful BLUE punch. Use as much or as little of each as you would like for taste and color.

Baby Blue Punch

1 gallon BLUE Hawaiian Punch
1 (2 liter) 7-up or sprite
rainbow sherbert

Mix hawaiian punch and 7-up.
Add round scoops of sherbert.

If you have time, you can make sherbert balls ahead of time (about the size of cookie dough on a pan) and freeze them so they are hard. This way the sherbert will not melt as quickly in your punch.
