How to make air propeller car | STEAM science project

In this project, we will learn how to make air propeller cars using basic techniques. This project is great for a maker space or mechanical engineering challenge at school, library, or home.

Once you learn the basics, you can experiment with different body styles and designs to make your car go faster. You can also set up a competition between friends to see who can build the fastest rubber power propeller car. Make STEM education fun!

Materials Needed

The good thing about this project is that you can get most of your “car” parts from the trash. You can use recycle bottles, ice cream sticks, and many trash items to create the body of your propeller car. Get creative!
For this project, you will also need the following materials:

• Straws
• Kabab sticks
• Switch
• Cardboard
• AA battery cell
• AA battery holder
• toy car motor
• propeller

required material

Required tools:
• Glue gun
• Knife cutter
• Scissor

Step 1: Car 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.

length measurement

cut the measured pieces

paste both the cardboard on one another


Step 2: Attach 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.

paste straw on card board

Pass the kabab stick into the straws leaving about an inch sticking out.

pass the stick from straw

Step 3: Mount 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.

Step 4: Add and make Motor Platform

Take the other cardboard and mark the 2cm" wide and 6.5cm" long 4pieces

mark the 2x6,5cm 4 pieces

bend the four pieces to make cube shape

bend the pieces to make cube

then paste on the car base

Step 5: Attach Battery holder, switch and Cell

Use hot glue, mount your battery holder, and cell to one end of the car.

add battery holder and cell

Step 6: Mount the motor

attach the motor on the motor platform, by the help of glue gun

Step 7: Connect the propeller

Push the propeller onto the shaft of the motor.

connect the propeller

Step 8: Wiring and Testing

Connect the battery holder, motor, and switch in series. Now your air propeller car is ready to test

add battery holder and cell
