Flowers are known for their colour, but there is one plant which remains normal, but as soon as water drops fall on it, its petals become completely transparent. This unique flower Diphylleia grayi is truly amazing. It is found only in America, Japan and China. The secret of nature and science is hidden behind this. The petals of this skeleton flower have air pockets, which convert light. When water falls on them, these air pockets get filled with water. Now this water and a fluid called cytolymph present in the petals mix, due to which light passes through it and there is no reflection. As a result the flower appears completely transparent
