Best Ways to Make Balloon Car
To make balloon car, you'll need a few materials and follow these simple steps:
Materials:
A large, round balloon
A plastic straw
Four plastic bottle caps
A lightweight, small cardboard box
Tape
Scissors
Markers (optional for decoration)
Steps:
Decorate the cardboard box as desired. This will be the body of your balloon car.
Attach the four plastic bottle caps to the bottom of the box, one at each corner, using tape. These will serve as the wheels.
Cut the plastic straw in half and tape one piece to the back of the box, vertically. Ensure it's pointing away from the box.
Inflate the balloon but don't tie it. Stretch the open end of the balloon over the untaped end of the straw.
Place your balloon car on a smooth, flat surface and let go of the balloon. The air escaping from the balloon will propel the car forward.
Experiment with the size of the balloon and the weight of the car to optimize its speed and distance.
