Troubleshooting Tips
Car Not Moving
Check balloon for leaks, ensure straw is securely attached, and verify wheels spin freely.
Wheels Not Spinning
Ensure axles are straight, check for friction in straws, and lighten the chassis.
Balloon Air Leaking
Secure balloon to straw with rubber bands, and check for holes in the balloon.
Chassis Unstable
Reinforce cardboard with glue, ensure wheels are aligned, and balance the car’s weight.
Customization Ideas
+Aerodynamic Chassis
Shape the cardboard into a streamlined form to reduce air resistance.
+Larger Wheels
Use bigger wheels for better traction and distance.
+Multi-Balloon Propulsion
Add a second balloon for increased power and speed.
