Each pendulum swings with a different period because of different lengths.
Patterns appear to emerge because of harmonic frequencies.
I was always more partial to chemistry tricks. They even have fire!!
We did something similar back in early High School Physics class to demonstrate to us gravity, energy produced and if I recall correctly, Newtonian Laws, as my teacher called it. It's pretty cool.
What? No, it's due to gravity. It's a demonstration of how different lengths of a rope affect the movement of the pendulum. Shorter strings produce faster movement, longer stings produce a slower movement. Put them together and you get this.

No the reason is quite clear and the system can be rather easily modeled with high school math.
I should get one of those.
A simple piece of string can entertain me for hours.
But 15 pieces of string...with billiard balls dangling....Heaven!
Nope,it happend for a sound physical reason, and can be duplicated in your own home to keep you entertained for hours

No - it happens because the pendulums (strings) are different lengths.
Duh.
What - you were thinking it was due to Jehovah magic or something?
LOL!!!

You'd think a science expert like Deeje would understand even the basics, but hen again....
She toys with us.
We're an ant farm in the sun, & she's the kid with the magnifying glass.
Or we're rats running thru her devious maze loaded with treats & traps.
Why would you think anyone would claim it happens for no reason? There are very precise, mathematical reasons underpinning this phenomenon.
But it does show how structure naturally forms even in very simple systems without intelligent intervention.
Well, rotation is one of the possibilities, no matter what. A lack of any rotation is unstable: even a little nudge will produce some rotation. And, because of conservation of angular momentum, any rotation will continue until some force (actually, torque) stops it.
What we do see is a wide variety of rotation rates and axes of rotation.
Cat owners will know the entertainment value of a single piece of string. A cat will play for hours with one end of a length of string and when the friendly feline gets fed up simply turn the sting over and you have a whole new toy good for hours more fun.

Weird that deeje abandoned this most excellent thread she started.

I saw that video as well.
They hid the fact that the strings are different lengths. It should have been obvious to me by their behavior but it's easy to be fooled, sometimes.
I saw the different lengths right away.
With an IQ of almost 70, I'm a keen observer.
Order never happens without intelligent direction according to my observations. Who created the laws governing what you call " natural" ? What is "natural" exactly? What happened to the law of cause and effect? You can ignore it when it suits?

Hey, I'm at least that smart. My friends all agree I'm smarter than the average picinic basket.
I'm rarely fooled and shouldn't have been with this one. But I saw a version that claimed it wasn't known why this happens and anyone can be thrown by a lie or by intent.
