The ripple patterns you see are created by surface tension — the same force that keeps raindrops perfectly rounded and allows small insects to stand on water. As the droplet hits, energy spreads outward in waves, creating a smooth circular vibration before settling into balance. The leaf’s waxy surface slows the spread, while the droplet reflects lig
