Materials-
- Balloon
- Wheels (thread rolls)
- Axles
- Soda Bottle
- Pencils
- Straw
- To start our design we will first make the wheels and axles by taking the thread rolls and attaching it to the pencils.
- The wheels must remain sturdy; therefore, putting tape on the sides of the wheels is a must.
- Take the side of the soda bottle and push the pencils through. Make sure to glue it on each side.
- Attach the wheels that were made by the thread rolls.
- Take a straw and place it in the mouth of the balloon. This will allow the balloon to release the air which will make the car go straight.
- Add the blown balloon to the top of the car.
- Once the balloon is released the air will exert an equal and opposite force that will cause the car to excel in a forward direction which is Newton's 3rd Law of Motion.
