Water drops are not easily slippery in roses. They also remain on other flowers and leaves, but the small vibrations make them fall (falling drops are a great cleaner for plants). In roses, however, much more violent vibrations are needed to drop the drops. The difference is in the microscopic structure of the surface of the petals, Japanese researchers have found. This structure has been used by researchers to manufacture non-slip materials. Seen

from the microscope it is understood that it supports water drops on the surface of the plants: small structures in the form of a superficial punch. But these nozzles are coated with wax, so small vibrations unbalance the drops and fall. In roses there is no wax in microscopic honeys. In addition, the 'dancers' between puyas help the petal to hold the drops. Therefore, do not slip the drops of water on the petals of the rosas.The structure is

interesting for other materials. Japanese researchers created a very thin film of polyvinyl alcohol polymer on pink petals; the polymer acquired the shape of the rose surface in the form of a petal and tested the film made through this system. The polymer also held water drops, as did the petals. Natural technology, form of synthetic technology.
