Thames & Kosmos WindBots: 6-in-1 Wind-Powered Machine Kit

Build six awesome bots that move without any batteries or electricity, just brain power, with the WindBots science kit for kids. Build a big wheel tricycle, quadruped, soaring machine, drilling monster, walking robot, and even a wind powered yacht. To make all of these fun machines go, the kit also includes the pieces to build a hand powered wind generator. The secret behind these fascinating machines is one of the oldest power sources in the world, wind! As you build and experiment, you will learn about how gears transmit power and torque. Ages 8+. 212 pieces. 6 experiments. No batteries or electricity required. 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.
