Loose Marble Toy
A marble is a small spherical toy usually made from glass, clay, or agate. These balls vary in size. Most commonly, they are about ½ inch (1.25 cm) in diameter, but they may range from less than ¼ inch (0.635 cm) to over 3 inches (7.75 cm). Various games can be played with marbles; One game involves drawing a circle in sand, and players will take turns knocking other players' marbles out of the circle with their own marble. This game is called ringer. Other versions involve shooting marbles at target marbles or into holes in the ground (such as rolly or rolley hole).
It originated in Harappan civilization in India near the river Indus. Various marbles of stone were found on excavation near Mohenjo-daro. Marbles are also often mentioned in Roman literature, and there are many examples of marbles from ancient Egypt. They were commonly made of clay, stone or glass and commonly referred to as a "Glass alley"
