Have fun while learning when you use this LEGO Gear Bots kit to build 8 STEM-driven models, including DJ Bubbles (an octopus spinning records), a pterodactyl, a yeti, and more. Each kinetic creation includes a paper craft character that you fold and link with the 62 LEGO elements included. When complete, crank the handle on the side and they move through a series of axles, cams, and levers. With colorful 64-page instruction book. Fun for ages 8 and up, it makes a great birthday or holiday gift.
