Students create balloon rockets by taping drinking straws to balloons and running a string through the straw. The ends of the string are held tightly apart. When the balloon is inflated and released, it moves along the string. Students use wire, yarn, twine and nylon string to create tracks for the balloons. This investigation explores the force of __________.
