Manu jumping is a water jumping sport practiced by the Māori people of New Zealand. Participants aim to generate the largest splashes when they enter the water. The technique involves diving into the water in a V-shape and then pushing their head downward to create a large air cavity. As this air cavity collapses, it produces a distinctive splash known as a Worthington jet.Our study explores the fluid dynamics involved in Manu jumping by examining various solid shapes with different V-angles and using an active robot that mimics the underwater opening of the body to create larger air cavities. Our findings reveal that the size of the splash is influenced by several factors, including the impact speed, body shape, and the active dynamics of the body underwater.
