A pogo stick is a device used for jumping and bouncing. It consists of a pole with a handle at the top, a footrest in the middle, and a spring at the bottom. When a person stands on the footrest and pushes down, the spring compresses and then propels them upward, allowing for a bouncing motion. Pogo sticks come in various sizes and designs, suitable for different ages and skill levels. They are often made of metal or durable plastic and can be used for recreational activities or as a fun way to exercise. Safety gear, like helmets and knee pads, is recommended while using a pogo stick.
