Wanna learn how to make the fastest balloon car racer? Let me know how you would like me to show you.
I have finished the build of my balloon car (for now) Link here I will be updating the stats over the next couple days.
Today I was able to build a racer that would drive straight. I will be refining the design over the next few days and will post the initial working prototype. The big issue that I believe to have resolved was the majority of the mass being to high for the wheel base. As the balloon deflates it would either lean left or right and alter the cars path. More details to come.
Put together my race car today. It was really low on weight and I was pumped.
-Too light or not enough downward force. Balloon flew off the ground when released.
-Added weight, went from 13.183g to 39.038g by adding a wing and quarters, stayed grounded and moved pretty fast.
Future design notes:
-Will be longer and wider. Thinking of a drag racer with a wider wheel base.
-Need to direct the way the balloon deflates, it redirects the car when it falls to the left or right.
I have started using a new straw for my car engine. See the details here and buy them from the link in the image below.
I have added more data and videos the the Nerd Out: Balloon Racer Car
I have added descriptions to many of the challenges in the cheap builds category.
Added an additional instructional extension to increase the engineering practices for higher level students.
