Electric Paper Plane Launcher

That's different.

"Have you ever wished that you could throw a paper aeroplane as straight or as far as someone else? This kit includes components to make two electric plane launchers — ideal for exploring different paper plane designs. The rubber discs spin at high speed and will launch a paper plane at up to 50Km/h (30mph). An ideal gift for any budding aeronautical engineer interested in the application of technology to problem solving."

Each launcher requires 2AA batteries (not included).

Age 8+ (most of my readers — sweet!).

$15.60.
