FeaturesBuild a working hovercraft that glides across smooth floors or flat water on a cushion of air. Learn how even though air is invisible, it still has mass and can support very heavy objects under the right circumstances. Experiment with propellers and impellers to learn about air pressure and air flow. The models in this kit use a unique blower motor and a safe, soft-bladed fan to drive a series of models. The blower motor uses an impeller to increase the air pressure under the hovercraft. The fan creates a stream of air to push the vehicle forward. Using these components, you can build and investigate the hovercraft and other machines that rely on air and air pressure to function. Construct a batting machine that tosses a ball upward on a stream of air. Assemble a basketball launcher and practice shooting hoops with air power. Make a fan-driven car that drives forward, propelled by a stream of air. Experiment to see how much weight your hovercraft can support. Full-color, 32-page experiment manual.
