Product Description
This is the original Slinky Spring from the USA for endless walking, juggling, flipping and action motion fun.
Invented 68 years ago by Richard James, a US naval engineer, the slinky idea came about when a tension spring fell off his desk and started “walking”. He then created a special coil spring and ended up selling 250 million in 50 years! It was even used as a mobile radio antennae during the Vietnam War.
Great for modeling transversal and longitudinal (sound) waves.
Size: 60 mm diam. in a box
