You don't need an expensive ice cream-maker machine to make the delicious concoction. All you need are one small and one large containers or Ziploc bags, ice cubes, some rock salt, and ingredients you like.
Put the icecream ingredients (milk, vanilla, fruits or chocolate, etc.) In a small container or Ziploc bag and seal it. Then put this container in a bigger container full of ice cubes and rock salt and seal it. Shake if for about 5 to 10 minutes, and presto, you have homemade ice cream!
