Principle	Description	About this toy
Top
Principle This toy is based on the force that can be saved in spring. This force can be used to rotate the wheels. This force also is transfered to release the bottom part of this toy to punch the floor and jump.

Description When a child winds the Jumping Car, it will move forward. The whole middle part just hangs on the two wheels, because the bottom part is the heaviest part of whole toy. The dotted lined part is what makes it jump. Before release the car, the dotted lined part should be pushed in the box. As it moves forward, the dotted lined part will punch the floor a while after the car is launched and therefore make it jump about an inch.

About the Jumping Car The Jumping Car makes use of cheap materials. This toy is made of plastic, coil spring, some gear mechanism, and rubber for the wheels. Because this doesn't use any expensive materials, the construction cost of this toy is very minimal. The only complex part of this toy is the dotted part in the bottom which punches the floor. Because this part always gets impact when a child plays with this toy, it is the part that can be broken the most easily. Because this moves around and jumps up and down, child older than 5 year old should be able to play with this toy, although it is a safe toy.
