Build a retro-futuristic train robot that actually “steams” using an ultrasonic atomizer—safe, cool water vapor illuminated by a fiery LED glow
Two builds, one kit: switch between a rolling locomotive and a walking robot in minutes
Powered by a real electric motor and control board; learn how mechanical motion, circuits, and gearing team up
Explore the science behind the effect: ultrasonic waves, phases of matter, fog vs. smoke vs. steam
Packed with maker-style fun: 116 pieces with snap-fit construction and clear step-by-step guidance
Story-driven learning: the comic-book manual turns assembly into an adventure and sparks curiosity
Designed for repeat play—rebuild, experiment, and tinker with different motions and looks
