About this item

  • BUILT TO MOVE! Kids ages 8 & up assemble a walking robot that’s powered by salt water and magnesium alone—no batteries required!
  • CLEAN TECHNOLOGY: When salt water is added to the magnesium fuel cell, it creates a chemical reaction that produces a flow of electricity to power the robot.
  • A LITTLE GOES A LONG WAY: An innovative pump mechanism provides a steady drip of salt water onto the magnesium plates; the robot walks up to 1 hour on just one drop of salt water!
  • LONG PLAY VALUE: The “fuel” (i.e. salt water) tank is easy to clean, refill, and reuse for hours of exploration, and the kit includes three magnesium plates, each with an operating time of about four hours.
  • EDUCATIONAL LESSONS, ENGAGING CONTENT: The 28-page, full-color manual guides assembly and experimentation and explores the science behind and benefits of non-toxic, long-lasting, alternative energy sources.
