does anyone know why grass seeds are able to trace out the E-field?
i was reading this http://www.oberlin.edu/physics/catalog/demonstrations/em/efield.html
i assume the oil is to reduce friction, and high voltages around 40kV are needed so the wimhurst machine is used?
but it doesn't really say why grass seeds react?
thanks
