The surface of a liquid at rest behaves in an interesting way, almost as if it was a stretched membrane under tension. A steel needle can be made to float on the surface of water even though it is denser than water. The surface of a liquid acts like it is under tension, and this tension, acting along the surface, is a product of attractive forces between the molecules. This effect is called surface tension. There are various methods to determine the surface tension coefficient of a liquid. This research focused on determination of pure water surface coefficient using Jolly's Spring Balance. The parameter measured is the height of the liquid bubbles at critical condition that in the right condition will break. Repeated measurement methods that are statistically processed are used to measure uncertainty. The magnitude of pure water surface value using Jolly Balance Spring Apparture's obtained γ (water) = (3,620 ± 0.0028) × 10^-2 N / m at temperature (27 ± 0.25)°C and pressure (68.8 ± 0.005) cmHg. Liquid used in this research is pure water at temperature 27°C.
