How can you make a Newton scooter move?


Quick Answer

One simple Newton scooter propels itself forward by ejecting air from a balloon. Attach a tubular balloon to the body of the scooter with the mouth facing backwards. When the air shoots out the back, the scooter will move forward, in accordance with Newton's law.

Step One: Build the Scooter

A well-built Newton Scooter operates with a minimum of friction and resistance to motion. Thus, the ideal model is lightweight, with attention paid to removing all excess wood pieces. To ensure that the wheels run smoothly, apply sandpaper to the axles. Wheels can be made out of old CDs, which produce very little friction.

Step Two: The Balloon

Balloons should be selected based on high air capacity and tubular shape. Once the balloon is selected, it should be placed on top of the scooter, parallel to the direction of travel. The end of the balloon should point towards the back of the car. To create a steady and direct air flow, insert a straw into the back of the balloon. This will maximize the forward thrust caused by the equal and opposite reaction that the Newton scooter is built to demonstrate. Ensure that the balloon is firmly connected so that all the thrust transfers into forward motion.
