Make an Ion Wind Rotor

This video tutorial demonstrates how to build an iron wind rotor using a Van de Graaff generator and simple materials like foil, nails, and electrical tape. The process involves cutting and assembling the rotor, ensuring it spins freely, and attaching it to the generator. The video explains the physics behind the rotor's operation, highlighting electrostatic charge and Newton's third law. It also discusses the importance of symmetry and the role of the pencil eraser in preventing the rotor from flying off.
