Turn paper airplanes into a fun and educational experience with the Electric Plane Launcher from 4M. This science kit includes materials children age 8 and up can use to make their very own paper airplane launcher. Kids will be amazed when they turn plastic disks and spinning motors into a device that can send a paper plain across the room at speeds of up to 50km/h! The Electric Plane Launcher is great for developing critical thinking and mechanical skills in young scientists. Have fun and experiment with different plane designs and see which ones go further or fastest! Kit requires 2 "AA" batteries (not included).
