Discovery Planet presents the latest in their Jr. Scientist series: the Strandbeest Kit that you build yourself! It has a very interesting mechanism: blowing into the fan makes the animal start walking against the wind. The wind power is conveyed to the legs by 2 gears. The 28-page science guide gives you the history of the real Strandbeest that Theo Jansen started building in 1990. The guide also includes easy-to-follow assembly instructions. For Ages 8+.
