To make a stress ball, slip a funnel into the neck of a sturdy balloon. If you want to make a firm stress ball, pour flour, baking soda, or cornstarch into the balloon. If you want your stress ball to be softer, use lentils, split peas, or fine play sand. You can also mix a little rice into your filling if you like.
