Rotating trampoline....
« on: August 16, 2019, 10:05:31 PM »
.....starting with  an artistic performance , at :
     https://www.thisiscolossal.com/2017/10/anonymous-dancers-demonstrate-the-mechanics-of-history-in-a-performance-by-yoann-bourgeois/
.....then with an extreme swinging(360*)/rotation , at :
     https://youtu.be/yGKhdsOdyy8
.....but thinking about a possible "kiiking" of a sliding mass-spring system , starting in the top position as an inverted pendulum and playing gravitational and radial acceleration in a "self" manner (longer arm freefall-shorter arm rise...or continuous variable pendulum )?!

.....on a "particular" springboard ,playing gravity and rotational inertia...as a swinging/rotating human variable "pendulum"...or Kiiking Performance , at :
     https://youtu.be/TWbcsEDrmFE
     https://en.m.wikipedia.org/wiki/Kiiking
     With an abstract expression (mass spring system mounted on a pendulum ) , at :
     https://youtu.be/z6_NRNw88Jw
.....can we play a "self" continuous rotation , due to an overpowered gravity ( with a spring in-out storage of the rotational inertia "assistance")?!

the magnetic field loves to be imbalanced
use that to your advantage
gravity is constant
combine the two
