A sandbox or sandpit is a small area filled with sand made for children to play in. Sandboxes are often rectangular with wooden sides. They can be installed in the gardens of homes. Sandpits are also very popular for making sandcastles. However, some animals use them for litter trays. Sandboxes can be found in most elementary schools. They can also be made of plastic, and in different shapes.
Sandpit
Beach Volleyball
The frame that holds together the playing field for beach volleyball, built on a solid surface of sand, is somewhat jokingly called the sandbox. This frame usually carries a board, possibly with advertising, and a net above it to hold back the ball.
About 150 t of washed quartz sand with a maximum grain size of 0.1 mm are used for a beach volleyball court.
