2 cans Hi-C (any flavor)
2 liter 7-Up
1/2 gal. rainbow sherbet

Make 2 trays of Hi-C ice cubes ahead of time. Combine remainder of Hi-C, ice cubes and 7-Up in punch bowl. Scoop in circles of sherbet just before serving. Stir slightly until frothy on top. Orange Hi-C seems to be the most popular. My boys love this made with green slimer Hi-C for an "eerie, slimey" drink!
