How To Make a Stress Ball

Get a small round balloon. Do not use water balloons; they are too thin.
Blow up the balloon until it is about 4-5 inches around, but do not tie it.
Pinch the top of the balloon shut an inch or 2 from the hole.
Place a funnel inside the opening of the balloon while pinching it shut.
Fill the top of the funnel with cornstarch.
Slowly let go of the top of the balloon so the cornstarch can slide into the balloon.
Continue adding cornstarch to the funnel until your balloon is filled to about 3 inches.
Pull up tightly on the opening of the balloon and pinch out any extra air.
Tie the balloon closed as near to the cornstarch as you can.
You can decorate your stress ball with stickers or permanent markers if you like.
Tips:
This project is easier to make with 2 people!
You might need to tap the funnel or stir the cornstarch occasionally to keep it moving into the balloon.
If you decorate your stress ball watch what kind of markers you use. Some markers will leave stains on your hands when you are squeezing the stress ball.
