How many kool-aid packets does it take to fill a gallon?

Well, isn't that just a happy little question! Typically, it takes about 1 cup of sugar and 1 packet of Kool-Aid to make a gallon of Kool-Aid. So, if you're using the standard Kool-Aid packet size that makes 2 quarts, you would need 2 packets to fill a gallon. Just mix it with water, give it a good stir, and enjoy the colorful sweetness!
