Make science spring to life with a whir of motors, levers, gears, axles, and propellers!

With six kinetic alien monsters to build, this kit doesn't just feed the imagination but, together with the science-packed companion book, it also explains all the physics and theories behind what makes the models work. This kit will teach children about physics, mechanics, forces, and motion without them even realizing it!

Together the models and the companion book illustrate in a lively and clear way how core scientific principles make things work, from thrust and friction to gravity and lift. And when kids have finished building their robot, they can decorate it with the included cool add-on card pieces that allow for hours of customizing fun!
