This research opens with the fundamental principles of capillarity. The rising of a liquid in a small diameter tube is affected by adhesive, cohesive, surface tensional and gravitational forces. The broadened definition of this phenomenon now brings other concepts such as capillary pressure and its role in natural and technological aspects. Applications of the capillary effect can be discussed in almost any growing science field, but this research focuses on the applications of water transportation in soil and plants, oil extraction from reservoirs and biomedical devices. What this research found was in every example, capillary action significantly improves results. In agricultural engineering, a more productive crop yield was observed due to cycling watering schedules based on a measurement through capillary action. Petroleum engineers can envision recoverable hydrocarbon areas based on capillary pressure. Biomedical engineers can now create low cost, portable devices due to capillary forces relating nature to science efficiently
