Ingredients and Materials
5 c. crushed ice
3 T. salt
1/2 c. whole milk
1/2 tsp. vanilla extract
1 Gallon-sized sealable plastic bag
1 Quart-sized sealable plastic bag
1 T sugar
Put the ice into the large plastic bag and sprinkle it with salt. Add the milk, sugar, and vanilla into the small plastic bag. Seal it well, removing as much air as possible. Place the small bag into the large ice-filled bag, making sure it is completely surrounded by ice. Seal the large bag and shake vigorously, or better yet, go outside with it and play "catch", but only throw it a few feet or the bags might get holes in them (You could of course do this in the house, but I would suggest only on hard floors in case it does break open). After about 5 minutes, take the small bag from the ice, open it, and then add any addition flavors (mint, chocolate chips, strawberries, etc.). Mix in the extra flavors and then get ready to eat!
Sheila Ellison suggests the following flavors and measurements:
Strawberry jam (1 Tbsp)
Chocolate Syrup (1 Tbsp)
I think that this would be a great activity on super hot days, or even cold days. Any day to eat ice cream is a good day to me. And if you have enough bags and other supplies, then each child/adult could make their desired flavor.
