As a child, were you fascinated by how things move? Do you wonder about new technologies and how they actually do work? Most children ask questions to ask. I, for one, know because my brother questions everything and he’s only 8 years old.

Have you ever had a birthday party? Well if you have you must have lots of supplies left over… In Innovation and Entrepreneurship Club last week, Group 1 students built BIRTHDAY BALLOON CARS from recycled party goods!!! To do this at home you will need:

  • One Balloon
  • Three Straws
  • Two Pens in which you can remove the ink

How to Make Your Own Birthday Balloon Car:

  • Remove the ink from the pens.
  • Cut 2 straws to be the size of the ink.
  • Tape one straw onto the end of the card and another one on the other end.
  • Using the nails make holes in the center of the bottle caps.

  • Tape the balloon to the straw. Make sure NO air can escape.

  • Tape down the straw to the card

Your Birthday Balloon Car is Ready to Race!!!!

What We Learned?

Students learned about alternative energy and sources. They built axles with wheels and learned how tires work on actual cars.  In these balloon cars, they learned about harnessing the potential energy in the balloon and using the change from potential to kinetic energy for your advantage. The energy released from the balloon propels the car forward.

In the end, all the students raced their cars in the hallway with all their parents cheering behind them. It was a great experience!! I had so much fun and cannot wait for our next project. For more information about GGKLI’s Innovation and Entrepreneurship Club click here!
