A variation on fiber spinning is the ductless or tubeless siphon, which is simply fiber spinning in reverse. A nozzle is dipped in a bath of the test fluid, a vacuum applied, and fluid sucked out of the bath. The nozzle is slowly raised, and a free-standing, rising colunm of fluid develops as shown in Figure 1.4. Sometimes the tubeless siphon is called a Fano flow, after the physician who first reported the technique (1908).
