which toy consists of a spring that can walk down stairs?
The toy that consists of a spring that can walk down stairs is called a Slinky. The Slinky is a classic toy that was invented in the 1940s. It is made of a coiled metal wire, typically in a helical shape, which allows it to stretch and compress. The Slinky’s unique design gives it the ability to “walk” down stairs by flipping and flopping from one step to another. When placed at the top of a flight of stairs and released, gravity causes the coil to extend and contract, propelling the Slinky forward and creating a mesmerizing cascading motion. The Slinky’s walking down stairs is a fascinating example of mechanical energy transfer and has captivated kids and adults alike for generations.
