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 fl ow.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. 32-page manual, 59 building pieces, 10 experiments,
