All aboard! Put on your engineer’s cap and build your own steampunk-style train robot with amazing steam effects.

With this STEM kit, kids can build the Train Bot in two different configurations, a rolling train and a walking robot. Turn it on and watch it go, with cool water vapor “steam” billowing from its chimney, lit up in a fiery orange glow. This retro-futuristic model is packed with modern technology, including an electric motor, LED lights, circuit board, and an innovative ultrasonic atomizer that transforms tap water into the fine mist that rises from the chimney.

Learn about how the ultrasonic atomizer works, about the differences between fog, smoke, and steam, and about the steampunk craze. The experiment manual includes step by step assembly instructions as well as a fun story that brings the Train Bots to life.

Thames & Kosmos was founded in 2001 by a science museum director and her son, who saw the great need and demand for better science education materials — resources for parents and their children that are more engaging, more effective, more relevant, and more fun.
