Plane Prop Demo

This demo grounds the plane concept in a real prop, showing how the prop’s path stays aligned to an invisible surface rather than just arm shapes. Using a single prop, Nikki Scarano contrasts wall plane (in front of you and behind you), wheel plane (shifted to the side), and horizontal plane (kept parallel to the floor/ceiling), with a simple wall–wheel–horizontal sequence to feel the orientation change.

Use it to self-check plane integrity by imagining a wall or ceiling the prop should never “crash” through. Then drill clean transitions between planes with arms only or any handheld object, focusing on consistent lines and controlled repositioning around the body.
