Build It Yourself Wind Power Generator Kit – STEM, STEAM Experiment for Learning About Renewable Wind Energy

Nice

Giving item 3 stars because was cumbersome to assemble and had difficulty getting propeller to adhere to the engine. Required trouble shooting at a much higher level than the children I was working with.

Horrible! Doesn’t work!

Disappointing. It functions, technically, but not how you would expect. The red LED flashes when it first spins, but that's it; it doesn't stay on while spinning. It required an adult to figure out why the LED would no longer light up once it was assembled into the plastic case (one of the leads of the LED was grounding out on the motor). The LED had to be twisted (which was NOT easy) so that it, and the motor, would fit within the case/housing. We had to use double-stick tape to get the water bottle cap to stick to the propeller cap well enough to spin the motor. This kit was more frustrating than fun.
