Very interesting video showing how a lotus leaf reacts to liquid. Notice how even honey slides off the leaf like water. Research is being done on material with a Lotus-like property, also known as superhydrophobicity.
Below is an image from a scientific paper published in 2008 titled Laser structuring of water-repellent biomimetic surfaces and fully available here. The image shows a comparison between the microscopic texture of a leaf and a surface shaped with a laser. The artificial lotus shows very similar behaviour (and appearance) to the real leaf. A group in Germany called “Lotus-Effect” is also working on the reproducing the magic and has published great documentaries on their website.
