What is a "jumping jack"?
A jumping jack is a type of toy that consists of a figure with moveable limbs, often made from wood or plastic, attached to strings. When the strings are pulled, the figure's arms and legs move in a jumping motion. The toy is often designed to look like a person or animal, with the action of the limbs creating a playful, lively effect. Jumping jacks have been popular for many years, especially as a traditional toy for children. They are enjoyed for their simple mechanics and ability to entertain with their repetitive, bouncy movement.
