K'NEX Rollercoaster - Fushigi

Hello Crazy Engineers, because of constructive feedback I have decided to create a K'NEX Rollercoaster that uses a Fushigi Gravity Ball instead of the standard K'NEX cars. I thought of the design while I was doing chemistry homework, and after I finished my homework I got to work. Two days later I completed it! Here is the video.

Thank You!
