       SpringBots: 3-in-1 Spring Powered Machines kit from Thames & Kosmos
  • Recommended for ages 6 years and older
  • Build a motorized robot, race car, and countdown timer that will run without any batteries or electrical power
  • The secret behind the machines is a power source called a mainspring- a spiral-shaped spring that stores up energy when wound up by hand, and then converts that stored energy back into motion when it discharges
  • The mainspring inside the robot turns gears which enable it to march forward on two legs (up to 20 inches)
  • The race car zooms across the floor as its mainspring uncoils and turns its wheels (up to 45 feet)
  • The countdown timer uses a more complex system of springs, gears, rachets, and linkages to slowly tick down the seconds as it discharges (for a countdown of up to 6 minutes
  • Includes over 130 pieces plus a full-color instruction manual
  • Kids will learn the physics concepts of potential and kinetic energy
