Train Bots

Build your own funky, steampunk-themed robots that use an ultrasonic atomizer to emit a safe, cool steam that mimics a real-life locomotive. Two robots to choose from: a rolling train or a walking robot; move a few pieces to go back and forth between each configuration quickly and with ease. An LED light illuminates the water vapor for a dazzling steam engine effect. Includes an electric motor, circuit board, and ultrasonic atomizer that helps teach kids about ultrasonic and sound waves as well as phases of matter. The 44-page, full-color manual includes a fun, comic-book-style story that adds to the play value of the kit and brings the models to life.
