It's that kind of day -- pouring rain, lots of outdoor fun scrubbed. Here's one of Kaboose's summer crafts projects for just this sort of day:

Ice Cream in a Bag:

What You Need

* 1 tablespoon Sugar
* 1/2 cup Milk or half & half
* 1/4 teaspoon Vanilla
* 6 tablespoons Rock salt
* 1 pint-size Ziploc plastic bag
* 1 gallon-size Ziploc plastic bag
* Ice cubes

How To Make It

1. Fill the large bag half full of ice, and add the rock salt. Seal the bag.
2. Put milk, vanilla, and sugar into the small bag, and seal it.
3. Place the small bag inside the large one and seal again carefully.
4. Shake until mixture is ice cream, about 5 minutes.
5. Wipe off top of small bag, then open carefully and enjoy!

Tips

* I always have sprinkles and nuts to top it off, and sometimes fruit.
* To make a larger amount I would try doubling the recipe. Anything larger might be too big for kids to pick-up, because the ice itself is quite heavy.
