Jumping jack (toy)

A jumping jack toy, c.1850

The jumping jack is a jointed, flat wooden figure, a cross between a puppet and a paper doll that is considered a mechanical toy. The figure's joints are connected to a pull string that causes the arms and legs to move up and down when the string is pulled and released. Jumping jacks were popular in many contemporary countries including England, France, and Germany, but similar mechanical toys date back to the Ancient Egyptians.
