1. A reservoir comprising:
a rod having:
a core component comprising a first single component fiber; and
a surrounding component comprising a second single component fiber;
wherein the core component has a first capillary force, and wherein the surrounding component has a second capillary force;
wherein the first capillary force is greater than the second capillary force; and
wherein the rod is configured to absorb and release a fluid by capillary action, and wherein the absorption and release of the fluid is configured to vary linearly along a cross-sectional diameter of the rod.
