About this project
We developed a formula that would turn a Slinky into an perpectual motion machine. Like watching a traditional Slinky tumble down an infinite staircase. The NESM is mesmerizing, relaxing, thrilling and aesthetically beautiful rolled into one.

i'm sure you're all aware of this classic Slinky movie scene from Ace Ventura - When Nature Calls. We just had to share it!
I always find myself fiddling, playing or staring at something, I find that inspiration comes from the most random of moments.
Everyone loves a toy that they can interact with, control or simply get lost in its motions, I think that’s why everyone has owned a slinky at some point in their life. Some of the best ideas have come from playing with a slinky, including this one (of course!) lol
If you would describe yourself as a day dreamer and are always thinking of a new idea or project to undertake… then you'll appreciate the awesomeness of this project.
That is why we want to aid the creative thinkers and the entrepreneur's of the world, because what’s better than a machine which blends science, art and slinky’s?
I’ve always had a slinky on my desk at work, to bend, stretch and occupy my hands in the presence of a problem. One day I was working on another project whilst playing with the slinky in my hands. The idea hit me, what if I could design a small, compact “Never Ending Slinky Machine”, something that occupies your hands and eyes whilst your brain wanders, imagines, dreams.
I was amazed at the story behind the Slinky and how it was born over 70 years ago, which involved education, physics, NASA and even the movies.
Founded in 1943 by Naval Engineer Richard James, and his wife Betty, the Slinky made its successful debut into the market in late 1945. The Slinky carried on its successes until 1998, when the company was sold to ‘Poof Toys’.
Over the years the slinky saw a catchy jingle and several successful advertisement campaigns, some of which can be seen below.
Not Just a Toy
- NASA used the Slinky to conduct zero gravity experiments whilst in space.
- U.S Troops in Vietnam used the Slinky to replace there broken radio antennae’s.
- Used as a teaching aid in classroom to show effects on gravity and waves.
- And let's not forget the sheer simplicity of watching your Slinky walk down the stairs.
The design brief was simple....
- To be a standalone beautifully crafted object in its own right
- To be powered by USB ports
- To be enjoyed by adults or kids
- To become a contemporary art piece for the modern office.
- To provide you with those momentary distractions from everyday boredom.
Project NESM was born almost a year ago now and what started off as a bit of a fun project on the side, soon became an obsession for everyone involved as it was a lot more challenging than first thought; probably why it hasn't been done before.
Prototyping Project NESM was particularly troublesome, as our first task was considering all the variables involved with making a slinky walk continuously in one spot (harder than you think), some of the variables include:
·What is the distance between each step?
·What angle does it walk most efficiently?
·At what metre/min does it walk?
·Keeping the Slinky Walking Straight?
Of course we’re not going to give you the exact slinky walking formula (that would be like giving away our secret sauce recipe), but we will give you an insight into the construction process of Project NESM, because we want to keep all our beloved Kickstarter backer’s informed.
After the slinky walking formula was collected we spent countless hours on prototype designs and variations on those designs, we felt that one stood above the rest. With a sloped Super Flex conveyor belt set at a certain angle this prototype proved to be both functional and efficient in its primary purpose of allowing a slinky to walk on a continuous spot, whilst also maintaining a design element that was aesthetically pleasing.
How is it Made?
In order to construct this prototype we have used some of the most cutting edge materials and techniques including the latest Aluminium Composite for the body and internal structure, using three awesome finishes of Sand blasted Aluminium, White and Black. Custom made rollers, shafts and brackets with 4 shallow groove bearings, then fitted with a silent running motor and gearbox, USB Cable and speed controller. Rubber Drive belt, Super Flex conveyor belt, and finishing it off with all Stainless Fastenings.
Although this is a well-engineered product with a vast number of component parts we have managed to keep the unit costs as low as possible.
We know you love to be creative, that's why we offer all our Kickstarter backer's the exclusive chance to purchase your Project NESM in a Build Your Own Kit form, the perfect way to let your creative juices flow. The ideal present for birthday's, Christmas or if you just want to treat yourself.
The Build Your Own Kit is available as an 'Add On' for only £5 extra (approx $8), and comes with all components, tools and a DVD containing full instructions.
As Project NESM is such a great looking feature on your desk (or coffee table), why not add that extra personalized touch for only £10 extra (or approx $16).
Custom Laser Engraving is available on all models and can be anything from a message of your choice to a company logo. All message's and logo's need to fit within a business card sized area (85mm X 55mm). You will be contacted at the end of the project to confirm design.
Every one wants the best or most unique product on the market, that's why we are offering you a Champion Edition at only £59 (approx $99 USD) for a September delivery or £65 (approx $109 USD) for a November delivery... This unique version of the NESM will only be available during project launch and comes in two stunning finishes: brushed stainless steel or brushed gold.
Each Champion Edition will come complete in your chosen finish and will have a unique serial number which proves its originality. The serial number is representative of print order. This edition is a one-off opportunity own a totally unique piece or art which is fun, mesmerizing and tough!
*Limited quantities of September delivery available, first come first serve.
Two shipments of the product will take place – one in September, one in November, which means each NESM be in backers’ hands just in time to give someone an incredibly cool Christmas gift!
I bet all you engineers and avid science fans didn't know the rules that govern the mechanics of a Slinky are due to Hooke's Law and the effects of gravitation.
Period of oscillation
Due to simple harmonic motion the period of oscillation of a dangling slinky is:
Where T is the time of the period of oscillation, m is the mass of the slinky and k is the spring constant of the slinky.
In the state of equilibrium of a slinky, all net force is cancelled throughout the entire slinky. This results in a stationary slinky with zero velocity. As the positions of each part of the slinky is governed by the slinky's mass, the force of gravity and the spring constant, various other properties of the slinky may be induced. The length of a perfect slinky with zero length when extended is:
Where L is the length of the slinky, W is the weight of the slinky, and k is the spring constant of the slinky.
Due to the forces of gravity, the slinky appears bunched up towards the bottom end, as the function of the position of a slinky is:
Where n is the dimensionless variable ranging from 0 to 1, 0 being the top and 1 being the bottom of the slinky, and each number between is the percentage of the slinky's mass above point n, and p(n) gives the position that n is in below the top of the slinky.
This quadratic equation means that rather than the center of mass being at the middle of the slinky, it lies two thirds of the length down, closer to the bottom end.
Project NESM is the brainchild of an ambitious team of UK designers & engineers, of which you can see below. All funds raised with Project NESM will go towards manufacturing and distribution of all NESM's and will help to accelerate the making of great projects.
Our long-term vision is to keep inventing, making and providing solutions to everyday problems.
Risks and challenges
Even the most meticulously planned projects can take a turn for the worse, but our experienced Creatables team was on hand to minimize these risks and challenges where ever possible, by considering every outcome. The most important thing for us is to control these risks and challenges by remaining very transparent throughout the entire project. If there are any problems or delays, we will communicate this to our audience straight away.
The biggest challenge for us was not the prototyping stage, but contemplating the production lead time. The delivery times set are staggered in two different dates to allow us sufficient time for delivery of NESM units, one batch will arrive in September 2014 for all 24hour specials, Early Birds and Original Plus – whilst the remaining batch will be received in November 2014 ready in time for Christmas!
In order for us to guarantee your Project NESM to you by Christmas at an affordable price, we need to be running fairly large volumes with very little wastage (as we expect a large number of units going out). Again this is all to do with scaling up the production; we have every faith in our experienced team!
