Begin by placing a small handful of candy inside the paper bag.
Next, blow up the balloon, but don't tie it yet. You want it to fit snugly inside the bag (on top of the candy), so you might need to adjust the balloon size by letting air out until it's just right! Once it is, go ahead and tie the balloon, and squeeze it in the bag.
Now tie a knot around the opening of the bag, enclosing the candy and balloon inside of the bag. After you've tied the knot, leave about 3 feet extra of string, before cutting it with the scissors.
Now it's time to decorate! You can turn this paper bag pinata into any animal or creature you would like. As you can see, I have decided to make a pig. Using construction paper and scissors, I cut out eyes, a nose, ears, and a mouth and glued them on the pinata with a glue stick. You can use markers instead or any other type of decorating material.
Before you can hang this guy up and whack 'em, you need to gently pop the balloon inside. On the back side of the pinata, carefully poke the pin inside the bag, popping the balloon.
