The principle this toy runs on is that of stored potential energy being converted into kinetic energy. The car stores potential energy in a stretched rubber band. When the rubber band is released, it will spin the rear axle and move the car. The car will come with rubber bands of varying sizes and elasticity. One rubber band may make the car accelerate quickly but for a short time while another rubber band will make the car accelerate slowly but for a longer amount of time.

After the child makes sure the pin is secure in the release mechanism, he will attach a rubber band to the hook and pull it back to the axle (the bottom of the car will be open to allow easy access). The child will start winding the back wheel up. The back wheel is connected to a ratcheting gear so it will not be released. When the rubber band is fully stretched, the child will pull the pin out of the release mechanism. This will release the ratcheting gear and allow the car to start moving.

This toy will be somewhat complicated to construct, which will make the cost increase. There are multiple moving parts which must be assembled inside of the car's mold. However, there are not any very complicated parts in the car so the individual pieces will not be expensive to make.

There are multiple moving parts in the car which will break with enough abuse. However the most complicated part of the toy (the release mechanism) is located high up in the enclosed portion of the car, so it should be protected from breaking.

The toy is not suitable for children under the age of 4. There are multiple small parts (the pin and rubber bands) which a small child could easily swallow. Other than the toy will be very safe. The front of the toy will be round enough not to risk impaling the child.
