Alright, so my mom discovered this one at a party for a new doctor in town. It is DELICIOUS!!! Feel free to change the Jell-O flavor. I've never tried it with anything except lemon, but I'm sure other flavors would be OK as well.

-Super Dooper Yummy Punch Stuffzzzzz-
4 c. water, 7 c. water
4 c. sugar
1 3 oz. Pkg of lemon jello (you can experiment with different flavors)
1 46 oz. can pineappple juice
2 or 3 2 liter bottles of lemon-lime soda pop (the cheaper, the more carbonation)

Mix 4 cups water and sugar in a large pot (8-12 quarts). Cook until sugar is dissolved. Stir often. Add jello mix and pineapple juice when sugar water is clear. Add additional 7 cups water and freeze.
When ready to serve, chop up in slushy pieces and pour lemon-lime over the top to desired consistency. Could take 2-3 bottles of pop per recipe.

Does it taste a lot like pinnapple? Because i LOVE pinnapple and I might try it if it does.

Well, it has a lot of pineapple juice in it
You can taste pineapple in it, for sure. I, personally, haven't tasted anything that I can really match it with, though. It's like this pineapply-sweet-Nirvana-summer-breeze-watch-Little-House-on-the-Prairie-and-flutter-in-the-sky flavor!
Yeah.
