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 less than one hundred nanometres, invisible to the naked eye.
Plant & Food Research uses this electrospinning process to produce nanofibre filters made from natural materials, such as marine collagen, for industrial use.
