This person poured red-colored water into a unique scientific glassware with a conical glass inside a jug-shaped piece. As the cone filled up, the water started pouring down to the jug through a loop, and once the jug had filled up, the water from the jug began pouring into the cone through another loop. To demonstrate the movement of the water, the person poured a carbonated drink and the bubbles started moving in a cyclical pattern.
