Children's handmade technology small production wind power mechanical beast 25*19*5cm

A relatively difficult environmental technology toy.
You need to assemble a lot of small accessories yourself, so it is recommended for children over 8 years old.
By converting wind energy into power, the mechanical beast can move.
It helps children understand the transmission principle of machinery.
Learn about the process of wind energy conversion and how it generates powerful power.
Understand the charm of new energy and cultivate children's awareness of low carbon and environmental protection.

Method 1: You can use a round paper fan, origami fan or electric fan to blow air at it, and the wind will drive the wind energy to make the mechanical beast move to the left.

Method 2: Use a pipe to connect the shaft and flange together. Remove the wind turbine from the wind power machine to prevent its weight from slowing down the movement, then insert the flange into the crankshaft and turn the shaft to start the wind power machine moving.
