Lime Fruit Slushies

I found this in a magazine. I haven't tried it yet, but it sounds like something my kids would love for a party or our next picnic.

• Ready In: 2 hrs 10 mins
• Serves: 12

Ingredients

• 3⁄4 cup sugar
• 1 (3 ounce) package  lime gelatin
• 1  cup boiling water
• 3  cups cold water
• 3  cups  unsweetened pineapple juice
• 1 (6 ounce) can  frozen orange juice concentrate, thawed
• 1  liter ginger ale, chilled

Directions

1. In a large container, dissolve sugar and gelatin in boiling water.
2. Stir in the cold water, pineapple juice and orange juice concentrate.
3. Freeze 1-2 hours before serving.
4. Stir in the ginger ale just before serving.
5. You may divide the mixture between two plastic containers before freezing. Once frozen, use them to help keep the items in your cooler chilled. They'll thaw to a nice slushy consistency.
6. You may want to adjust the amount of sugar to your liking.
