The wide array of Slinky Spring offered by us is highly in demand in the market. This revolutionary toy comprises of a helical spring that stretches and bounces up and down. It can travel down a flight of steps end-over-end as it stretches and re-forms itself with the aid of gravity and its own. Slinky Spring is used to simulate the properties of waves. United States troops in the Vietnam War used them as mobile radio antennas, and NASA has used them in zero-gravity physics experiments in the Space Shuttle.
