My son really enjoyed building this kit. It spins faster than I thought it would when in direct sunlight.

Fun project!
My little one loved this project. Her older brother was able to read the instructions out to her & she used her project for science fair. Very easy to understand/build/assemble. I didn’t have to help not once! Very fun project. Functions well in sunlight.

Super fun activity
This is so fun. Was a challenge to assemble for my 7 year old, but kept him focused for a while! Itâs paired great with the study unit we are working on this semester on weather.

Solar windmill
The model went together nicely and looks very nice when completed. The windmill runs smoothly when the sun hits the solar panel straight on.
