TrainBots: 2-in-1 STEAM Maker Kit

• 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
