Everyone loves a Slinky®! This original metal spring toy is famous with kids of all ages. It stretches, snaps back, and makes a "slinkity sound." [Do you remember the Slinky song?]

A Slinky® is a fascinating spring. What differentiates it from other springs is the amount of stretchiness compared to its mass -- the ratio of 'spring pull' to 'spring mass' is small compared to a common spring. Scientists refer to this as the spring constant to mass ratio, written as "k/m".

The Slinky is so loved that there is an entire web site, http://slinky.org, devoted to nearly every conceivable aspect of this toy.

The spring diameter is about 3" (7.6 cm).

WARNING! This toy presents a potential hazard for young children. Do not give to a child under 3 years of age.
