Mix Jell-O according to package directions, and pour into individual clear cups about 1 inch high. Refrigerate until set. In a large punch bowl, add Sprite or 7up, pineapple juice and scoops of sherbet. Let flavors mesh for 10 minutes. Spoon punch and scoop sherbet into each cup. Sprinkle strawberries for garnish, and top off with a bubble tea straw. Enjoy! Note: if you have leftovers, place in pitcher and refrigerate. It tastes just as delicious the next day.
