Aerodynamic kit

This 3 in 1 kit will allow you to experiment with the laws of fluid mechanics. Once assembled in seconds you can use the main module to blow on one side or vacuum on the other. The blower on the top will allow you to magically levitate a polystyrene ball or even blow bubbles. By connecting a small hose on the suction side you will convert the device into a mini vacuum cleaner. To be completed with 2 AA batteries and bubble liquid.
