Ball pit

A ball pit (originally called a ball crawl, also known as a ball pool or ball pond) is a padded box or pool filled with small colorful hollow plastic balls generally no larger than 3 inches (7.6 cm) in diameter. They are typically marketed as recreation and exercise for children.

They are sometimes found at nurseries, carnivals, amusement parks, fun centers, fast-food restaurants, and large video arcades, frequently incorporated into larger play structures such as mazes, slides and jungle gyms. They may be rented for parties, and smaller versions are sold for home use.^[1] Ball pits are also sometimes used in therapy and educational settings, as they can provide a stimulating and sensory-rich environment.^{[2][better source needed]}
