You might remember that Slinky was first caught exercising in this viral video from 2012. But now, London-based Creatables Labs has given the springy toy something to work out on that's more its size.
When they were developing the NESM, they set out to make a "beautifully finished machine" so the famous walking spring toy could continuously walk, until you stop it.
"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," Creatables Labs' founder of Craig McCormack says.
"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."
It works like this: Plug the NESM to a power source through a USB, plunk a Slinky on its belt, turn it on, and prepare to waste the rest of your day watching your coiled steel plaything getting its heart rate up.
