I don't know why it's claimed the chain fountain effect was discovered in 2013. I found it ages ago. So long ago, I forget when. I'm not claiming I discovered the effect either - because it's far older than I am.

All you need is one vertical orientated sprocket and a long loop of chain. Rotate the sprocket to drive the chain and observe the dangling loop of chain - similar effect. The effect also works with drive belts - consider old farm machinery driven by steam tractor or mill machinery powered by long flat belts.

They all exhibit 'strange' motion akin to the 'chain fountain' effect.
