Build STEM-driven models, such as DJ Bubbles (an octopus spinning records), a pterodactyl, a yeti, and much more! Kinetic sculptures, or automata, are mechanically engineering toys that move when you crank the handle on the side. They move through a series of axles, cams, and cranks that work like the pistons in an engine. Each model includes a papercraft character that you fold and link with LEGO elements. Comes with: 64-page book of ideas and inspiration, 62 LEGO® elements, 10 sheets of papercraft. | LEGO Gear Bots by Editors of Klutz, Boxed Set/Slip Case/Casebound | Indigo Chapters
