Two students are tossing water balloons. Student A throws a water balloon underhanded to Student B. As Student B catches the balloon, he cradles it by slowly decreasing the balloon's speed over a long time interval before the balloon stops. When the balloon is thrown back, Student A quickly grabs the balloon, and it pops in her hand. Compare the catching methods of each student. If the balloon had the same change in momentum, why did the balloon pop in Student A’s hand but not in Student B’s hand, and how should Student A change her catching technique to avoid the balloon popping?
