How to Build a Ballon powered car using Air Pressure Experiment. (The BackGround)

A pressure means a force. It is a pull or a push. The force of the air in the balloon is what drives the car to move.

In this activity you will learn some physics concepts and use recycled materials to build a toy car that is propelled by a balloon. You can even find a friend, build two cars and race them against each other. Whose car will go the fastest?

Background It might not seem like it at first, but a simple balloon car is loaded with physics and engineering concepts! When you inflate a balloon, it stores potential energy in the form of stretched rubber and the compressed air inside. When you release the balloon, this energy is converted to kinetic energy—the energy of motion—as the balloon zooms around the room. Some of the energy is also converted to heat due to friction. According to the law of conservation of energy, the total amount of energy is conserved. Energy never “disappears”—it just changes to another form.

Blow through the straw to inflate the balloon, then put your finger over the tip of the straw to trap the air. Kindly subscribe and watch out for the next articles on the materials used and the Procedures
