a geyser in Wai-o-Tapu
The Lady Knox is a geyser in Wai-o-Tapu, situated in the volcanic area of Taupo. It is named after Lady Constance Knox, the second daughter of Uchter Knox, Governor of New Zealand. Eruptions produce a water jet that reaches 20 meters and can last for over an hour. The geyser has two cameras of water, one hot, and one cold. The low one is heated due to volcanic activity below. When soap is cast into the water chamber superior, the surface tension of water lowers, allowing it to mix with the hottest water below, causing the eruption.
