Why water droplets stick to rose petals?
observing rose petals with water droplets glittering in the sunshine, some researchers in China wondered why the water droplets stuck to the surface of the petal. Even when they turned the flower upside down, the droplets didn't fall off. "We work on the interaction of solid surfaces with water, including natural surfaces. When we saw rose petals with water droplets on them, we picked some petals for study,' said Lin Feng, the lead author from the department of chemistry, Tsinghua University,China.
Research followed observation and what has come to light is the petal effect
