## Description

Product Description Product Description Blast down the stairs, jumps from your hands, springs from table tops and much more. This is a pre-compressed helical spring, that can perform a number of tricks, most famously travelling down a flight of steps end-over-end as it stretches and re-forms itself with the aid of gravity and its own momentum. It can also appear to levitate for a period of time after it has been dropped, and make spooky sound effects As well as being a classic toy, the design has appeared in the classroom as a teaching tool, in wartime as a radio antenna, and has even been used by NASA in zero-gravity physics experiments. It can be used to show the principles of Hooke's law, to simulate the properties of waves and demonstrate the effects of gravity. Popular Science publication has been a leading source of science and technology since its inception in 1872. The Popular Science range of toys, gifts and gadgets are designed to promote learning in STEAM (Science, Technology, Engineering, Art, Mathematics) and include information with each product that relates how they work or what they do to the science around us and in our everyday lives.

### ⭐⭐⭐⭐⭐ Works on the stairs and feels great in your hands
*by A***D on 27 July 2025*

Brilliant, perfect 5th birthday present and so satisfying. A real slinky that even a newly turned 5 year old can send down the stairs.

### ⭐⭐⭐⭐⭐ Best slinky
*by A***R on 10 January 2026*

Great product!

### ⭐⭐⭐⭐⭐ Great spring for the stairs.
*by A***N on 14 January 2025*

My son 7 years old bought a cheap plastic rainbow spring from a school sale. He was truly upset that it didn’t work down the stairs, the whole thing basically tumbles down the stairs and may as well not be a spring. Decided to buy a metal spring in the hopes for a better display. My son was not disappointed, this spring works great on the stairs, looks impressive and I do like the sound of the spring (metal on metal). I do second what others have said, it’s probably too long for any tricks in between hands, but honestly I bought it for my son who likes to use it on the stairs and for that I can’t imagine a better spring.
