383: Slinky

Posted by wonko on March 20, 2012 in geometry |

Now I am a fan of a simple but effective modular, and this one is a lot of fun:

Modelled after a spring-slinky, designed with skill by Jo Nakashima, it stretches, falls and steps like the real thing.

Using remarkably simple modules, each from a small square, the structure begins to behave when there is sufficient mass in it to be propelled by its own momentum.

I like this model a lot – it was a fun way to while away an exam supervision and the construction method was simple. I ended up making over 50 modules before it started behaving correctly but even this feat did not take very long.

Give it a try, you know you want to…
