1.The blades on an airplane take the air that is standing still and pushes it backwards. The wind pushes the rotors on the angled parts. It pushes one way making it go around.
2. If the blades weren't twisted the wind would just push on them and they wouldn't spin.
3. They both catch the air and use it to push them.
4.Madison and Kirsten's rotor
5. it was longer with skinnier blades. it had more of an angle than ours
6. Some limitations of our windmills are flimsy blades. They would start to bend if there was wind and it wasn't turning
