Failure #1

I set out to experiment with effective randomness of multiple penduli. Using found materials and some string brought back from Korea, I set out to construct a scaffold to hold several.

I observed that the more pendulums involved, the more random the motion: one pendulum was very regular and predictable. Two pendulums would cross and intersect, winding up around each other, then unwind and upon separating begin all over again.

Three pendulums would have more erratic behavior. The weight would bend the scaffold more as they moved, introducing new movement. Two pendulums would intertwine, leaving the third to move freely.

The more pendulums, the closer visual approximation of chaos.

I also experimented with pulsing one stick with three penduli - moving the stick in a regular up and down motion - simulating a mechanized movement that might be sustained throughout an exhibition. The results were even more interesting. As they began to swing in resonance with the pulsing, they began to wrap themselves around until they could no longer move. This became a dynamic to random state, the equation equal to zero. Very much the opposite of what I was trying to accomplish.
