Our Final Balloon Car (Design Process)

Claire and I finished our balloon car! (:

The materials we used were:

• Two skinny straws
• One fairly wide straw
• One balloon
• Four round blocks from an old toy chest
• Two skewers
• One square piece of cardboard
• Hot glue gun
• Tape
• Scissors

We did not have to buy any of these items in order to make our cart. We simply used items found around my house. In the end, $0 was spent on car parts for the building process.

Throughout the building process, Claire and I got some help from my parents. My mom helped me find the four wheels to use for the car. And my dad helped me figure out how to make the car accelerate using the wide straw and a balloon. I can't wait to do my first trial of the car. I hope everything goes well!
