July's Science Minute
Ice Cream in a Bag This science minute will take longer than a minute, but you end up with some sweet rewards. You only need 7 things: Half and Half - Whole milk will make a less creamy ice cream. Mixing whole milk and cream can make a creamier ice cream. Half and half is the easiest blend, but feel free to experiment to find the texture you like. Vanilla extract Sugar Salt - You can use any salt you have around the house, but the chunkier salts are easier to keep out of the ice cream. Ice Two sizes of high quality plastic bags like Ziploc - You want a good seal, especially on the smaller bag to help keep the salt water from getting into the ice cream mix. Inside the smaller bag, pour 1 cup of half and half, 1 Tablespoon sugar and 1.5 teaspoons of vanilla extract. As you seal the smaller bag, squeeze the air out.
