To form air-stable threads using the 2NapFF solution, a small amount of solution was dispensed onto a surface and then pulled vertically while slowly dispensing the fluid, resulting in a liquid thread being formed. Part of the solution was anchored to the surface, which facilitates stretching of the thread as it forms. With a liquid thread running from the surface to the end of the dispensing tip, the thread is then bridged across a gap. The dispensing tip can then be touched onto the surface of the beaker to 'break' the thread. If this is not done, the thread behaves like a rope and will be pulled off the bridge. f Bristol Centre for Functional Nanomaterials, HH Wills Physics Laboratory, University of Bristol, Tyndall Avenue, Bristol, BS8 1TL, U.K.
