Next, use a funnel to fill up a balloon with either rice or couscous. Tie it off.
You’ll then want to cut rubber bands in half (you won’t want to use rubber bands that are too skinny) and tie them together to make a rubber band rope.
Cut a slit toward the small opening of your milk jug. Tie one end to the jug and the other end to the balloon.
Enjoy! I got this fabulous idea from A Mom with a Lesson Plan.
