A child's toy is an object used by children for entertainment and play. Dolls, rattles, tops, whirligigs, wagons, playthings, hoops, yoyos, popguns, scooters, jumpingjacks, and jackintheboxes are all examples of toys that have been popular with children throughout history. Dolls are small figures made of cloth, plastic, or porcelain, while rattles are objects that make a noise when shaken. Tops are spinning toys that can be made of wood or plastic, and whirligigs are wind-powered toys that spin in the air. Wagons are wheeled vehicles that can be pushed or pulled, and playthings are any type of toy that can be used for play. Hoops are circular frames that can be rolled along the ground, and yoyos are two-piece toys that can be spun around on a string. Popguns are toy guns that shoot out a cork or other projectile, and scooters are two-wheeled vehicles that can be ridden. Jumpingjacks are wooden figures that can be made to jump up and down, and jackintheboxes are toys that pop out of a box when a handle is turned.
