What inspired you or what is the idea that got you started?
This unique technology is not described in textbooks, but I think it is cool so I wanted to share it with the world while I have the opportunity.
What is your project about and how does it work?
This project is about how to build a system that looks like a normal hula hoop but uses science and engineering to make the hoop overcome gravity and go up a pole.
This video shows the secrets of how the machine works:

What did you learn by doing this project?
I learned how involute gears work and how to make them. I also learned how much fun it is to successfully design and build a unique and amazing machine. And finally, I learned how rewarding it is to share unique knowledge in such an interesting way.
What impact does your project have on others as well as yourself?
This machine definitely sparks interest and delight in people who see it. I know I like watching it in action, it is a little mesmerizing and mysterious even when you know how it works. Hopefully, it also inspires others to get enthusiastic about STEM subjects so they can experience the thrill and satisfaction of being able to design and build awesome devices.
