Toy Car Air Pump
Interaction : Children can place their favorite toy cars into the bay of the pump. A large round top is then pounded in order to force air out from behind the car in the bay. This will cause the car to accelerate rapidly. Children can play with these side by side and have races or they can be used for other creative car games.
Toy Principle : The force of air pushes the car into motion.
Durability, Safety, etc : This toy will be constructed entirely out of cheap plastic. A very durable plastic should be used especially for the area that receives the impact of the pounding on the top. If not, severe wear and tear would quickly destroy the pump. One possible concern would be the speed at which the cars shoot out from the pump. This could cause injuries if the car is directed at an individual.
