These open channels are potentially useful for fluid management at low Bond numbers. The experiments were performed in a Plateau tank, injecting 2-fluorotoluene into distilled water, density matched at 26.5 $^{o}$C. Extension springs with a nominal diameter of 0.24 inches and with a wire diameter of 0.018 inches were used. At small extensions, liquid can be injected into the spring from one side. The injected free-ended liquid columns are stable.
