Air-Stream Machines Kit

Age 8 and up. Build classroom excitement with this kit. Students construct a working hovercraft that glides across smooth floors and still water on a cushion of air. They experiment with propellers and impellers to learn about air pressure and flow.
 
Kit includes multiple projects, such as building a mini batting machine, basketball launcher, and fan-driven car. Also includes a 32-page, full-color experiment book.
