Making a balloon car is a fun craft project and educational science experiment that can be done with kids. This activity can be used to help teach kids how wind energy can be used to propel an object, as well as other principles in physics like momentum, force, friction, and speed. It's also a great lesson in recycling and how to re-purpose waste items into fun toys. You'll only need a few simple materials: some sort of base, straws, skewers, tape, and a balloon.

If this is a group or class project, have the kids measure whose car travels the furthest or fastest. This is a great way to demonstrate the scientific method and develop different hypotheses about how to improve the car.

It is best to use a round balloon rather than a long skinny one. It will condense the air and give you more force.

Make your car more aerodynamic (slick and straight so it can cut through air and go faster) by playing around with different materials, wheels, and other design features.

If you want to make a balloon car, use scissors cut a rectangle out of cardboard. Cut 2 pieces of straw a little wider than the cardboard and tape them to the cardboard, then slide 2 pieces of wood into the straws to hold the wheels. Punch a hole in the tops of 4 bottle caps to act as the wheels and slide them onto the wooden sticks. Next, tuck a straw into the mouth of a balloon and tape it in place securely, then tape the straw to the top of the car. Blow some air into the balloon and set the car on the ground so it can roll! If you want to learn how to make the body of your car with a water bottle, keep reading the article!
