Pinwheel Balloon
Looking for something to keep the kids busy this summer? Using a few ingredients from around the house you can create the pinwheel balloon.
INGREDIENTS
- Pencil with an Eraser
- Sewing Pin
- Balloon
- Tape
- Flexible Straw
INSTRUCTIONS
STEP 1: Put the long end of the straw into the opening of the balloon. Using the tape, secure the balloon onto the flexible straw.
STEP 2: Push the sewing pin through the balancing point of the straw to the eraser.
STEP 3: Bend the flexible straw at a right angle. Inflate the balloon by blowing into the straw and observe.
EXPLANATION
Newton’s third law of motion says for every action there is an opposite and equal reaction. As the air rushes out of the balloon the opposite and equal reaction is for the balloon and flexible straw to spin.
