First invented in the 1940s, the loosely coiled, silver metal spring toy can be satisfyingly poured from hand to hand, walked down the stairs or slopes, or generally be fiddled with! The traditional toy can be used for hours of springy fun or even for scientific experiments and demonstrations. It's fun for children and therapeutic for adults and comes packaged in an illustrated kraft box.
