Electrospinning rainbow

A bead of polymer solution forms on a micropipette tip. Electrostatic forces draw a thin jet of liquid out of the pipette until it reaches terminal velocity and whips into a fast moving spiral, creating a rainbow of colours. The fibre eventually stretches to a width of less than one hundred nanometres, invisible to the naked eye.
