A table tennis ball is a small, lightweight ball used in the sport of table tennis (also known as ping-pong). It is typically made of celluloid or plastic, is spherical in shape, and weighs 2.7 grams. The ball has a diameter of 40 mm and is hollow, allowing it to bounce well on the table. It is usually white or orange, with a matte finish to reduce glare during play. The ball is designed to be fast and responsive to the spin imparted by players using their paddles.
