Science Powered Zen Garden.

I’ve always appreciated the simple beauty of Zen gardens, mostly from afar as my natural instinct is to run directly to the perfectly groomed sand and mess it all up. That being whilst I may have kindled an interest in gardening recently (thanks to my wife giving me some chilli plants for Christmas) I have very little interest in creating one of these myself, even of the desktop variety. The video below however demonstrates a kind of Zen garden that I could very well see myself spending numerous hours, mostly because it’s driven by some simple, but incredibly cool, science.

On the surface it seems like a relatively simple mechanism of action, two steel balls roll their away across the sand and produce all sorts of patterns along the way. The reality of it is quite a bit more interesting however as, if you watch closely, you can see that the two steel balls’ motion is linked together around a single point of motion. This is because, as Core77’s post shows, there’s only a single arm underneath the table which most likely houses 2 independent magnets that are able to slide up and down its length. In all honesty this is far more impressive to me than how I would’ve approached the problem as it makes producing the complex patterns that much more challenging. If it was left to me I would’ve had a huge array of magnets underneath the surface, but that seems like cheating after seeing this.
