Hi, some of the drinks I've done in the past are, shirley temples, milk shake, smoothies and put some colorful sprinkles on them (adds a little birthday touch). Here's a reciepe that's really fun, kids love the color and who doesn't love slushies? It's called a "sinister slushie" 4 bottles brightly colored sport drinks, 4 to 8 cube trays, Resealable plastic freezer storage bags.
1)pour sport drinks (red,blue, yellow, and green are fun colors)into separate ice cube trays and freeze overnight.
2)Just before serving, pop frozen cubes into plastic bags, one color at a time. Seal bag and smash cubes with rolling pin.
3)Layer different colored ice slush in clear glasses to make wild combinations, serve with straws.
It has been a big hit at parties.
Good luck and happy party, L.
