NOCODUSA on Instagram: "How frequency can change water flow is one of the coolest examples of physics you can actually see with your eyes. When sound waves or vibration frequencies hit water, they create pressure variations that force the water to move in repeating patterns. These vibrations push and pull the water molecules in rhythm, causing waves, ripples, standing patterns, and even shapes that look unreal. This effect is part of cymatics, a field that studies how sound influences physical m
