Title: Rotating trampoline....

.....starting with  an artistic performance , at :

.....then with an extreme swinging(360*)/rotation , at :

.....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 :

     With an abstract expression (mass spring system mounted on a pendulum ) , at :

.....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
