Project Story
What I made
In this project, you will learn how to make a simple air propeller car using cardboard, straws, kabab sticks, a small DC motor, a battery, and a propeller.
This is a fun STEAM project for schools, makerspaces, libraries, and home learning. It helps students understand basic engineering, motion, force, friction, air thrust, and simple electric circuits.
Why I made it
students can test different body shapes, wheel sizes, and propeller positions to see how they affect speed and distance. This project can also be turned into a friendly classroom competition.
What I learned
How air thrust moves an object
How wheels and axles reduce friction
How a simple electric circuit works
How motor direction affects movement
How design changes can improve speed and performance
Materials & Components
Components Needed: Cardboard Straws Kabab sticks Switch AA battery cell AA battery holder Toy car motor / DC motor Propeller Wheels Tools Needed: Glue gun Cutter Scissors Ruler Marker
How to Make It
-
1Car Body -The first thing you need to do is to measure the cardboard of approximately 4-inch″ wide x 6-inch″ long. This section will be the base of the car. -cut the measured pieces -paste both the cardboard on one another
-
2Attach the axle -Paste the straw on the base of the car. Make sure the straws are wider than the base which will help the wheels from the contacting cardboard. -Pass the kabab stick into the straws leaving about an inch sticking out.
-
3Mount the wheel -Now it’s time to mount the wheels on the axle of the propeller car. If the wheel is a little loose, you will need to add hot glue to the middle. Make sure the wheels are kept as straight as possible while the glue is hardening.
-
4Add and make Motor Platform -Take the other cardboard and mark the 2cm” wide and 6.5cm” long 4pieces -bend the four pieces to make cube shape -then paste on the car base
-
5Attach Battery holder, switch and Cell Use hot glue, mount your battery holder, and cell to one end of the car.
-
6Mount the motor attach the motor on the motor platform, by the help of glue gun
-
7Connect the propeller Push the propeller onto the shaft of the motor.
-
8Wiring and Testing Connect the battery holder, motor, and switch in series. Now your air propeller car is ready to test
