⚙ Under the hood

Tap or click the water in a top-down view of a bathtub to splash ripples outward. The ripples spread across a real wave-equation grid, bounce off the tub walls, and pass straight through each other (superposition), while wave-speed and damping sliders let kids see how fast ripples travel and how quickly they calm down.
