Introduction

We all loved playing with racing cars. But have you thought of building your car? If you haven’t, don’t worry, this science project is especially for you. So, in today’s article, we’ll learn about how to make a balloon car. Let us begin.

Supplies

Let us now have a look at the resources required to make a balloon car.

Tools

• Scissors
• Tape
• Pencil

Materials

• Scale
• Balloon
• Cardboard
• Bottle Caps
• Straws

Steps To Make A Balloon Car

Step 1: In the first step, we have to take a ruler and measure two pieces of straws equally and use a scissor and cut the straw into two pieces, and these pieces will be the axles of the car.

Step 2: Use cardboard as a base of the car and tightly tape two straws under the base with the help of double-sided tape.

Step 3: Take the balloons and use the scissors to trim the mouthpiece of the balloons.

Step 4: Slowly slide the straw inside the balloons about 5 cm and use the tape to make an airtight connection.

Step 5: Now, turn the base so that the straws are towards the bottom side. Choose the rare direction for the car and place the straws towards it. Use double-sided tape to secure the straws.

Step 6: Take the flat end of the skewer and measure it to 10 cm and then cut it by using the scissors. Slowly slide them into the straw attached to the base.

Step 7:  Take the bottle cap and draw four circles on the cardboard. They will be the wheels of the car. Use the ruler to draw two diameters of every wheel. Make sure you mark the center point. Now cut the wheels of the same size.

Step 8: Now attach the wheels on the parallel axles in the centered holes. Make sure the wheels are parallel and perfectly aligned.

Things To Remember

• The tape needs to touch both the balloon and the straw.
