## 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.

### ⭐⭐⭐⭐⭐ a CLASSIC SLINKY - go on - you know you want one.
*by M***E on 2 February 2026*

the BIG slinky - clear the stairs, it never stays in its box long when the grandkids arrive, and keeps them occupied for ages. Developed by a US Navy engineer doing some design work in 1943, they first went on open sale in 1945 for $1.00 each, and were an immediate success.
