Scientific explanation for water rising phenomenon at Hoover Dam

Videos circulating on social media show water poured from a bottle at the Hoover Dam appearing to flow upward. The Hoover Dam is located in the Black Canyon of the Colorado River, on the border between Nevada and Arizona in the United States. Scientific analysis confirms that this phenomenon is not a violation of gravity, but rather the result of aerodynamic forces. Strong winds moving through the canyon strike the curved wall of the dam, creating a powerful updraft. This rising air is sufficient to lift small amounts of liquid, such as water from a bottle, upward along the face of the structure. The design of the dam is specifically responsible for channeling these currents. This effect is a documented physical interaction between the structure's architecture and local weather conditions.
