The "Human Hamster Ball" is a large, inflatable sphere designed for people to climb inside and roll around in. Typically made of durable plastic, these balls allow individuals to experience a unique form of movement, similar to how a hamster moves in a hamster wheel. They are often used for recreational activities, events, and team-building exercises. Participants can roll downhill, across water, or on flat surfaces, providing a fun and exhilarating experience. Safety features, such as harnesses and air cushioning, are usually included to protect users during their adventures. The activity is popular at amusement parks, festivals, and outdoor events.
