What is the carnival ride that spins and the floor drops out?

The carnival ride you’re referring to is often called the "Drop Zone" or "Disco Drop." It features seats arranged around a central column that spins while the floor beneath the riders drops away, creating a thrilling free-fall sensation. As the ride spins, the sudden drop and centrifugal force enhance the exhilarating experience. This ride is popular at amusement parks and fairs for its adrenaline-pumping thrills.
