"The photo above provides a wonderful demonstration of the physics of light in water drops as well as the attraction of water molecules to plant molecules and to one another. In this case, the liquid drops result from rain and fog. A drop of liquid behaves like a simple lens – just like a camera. Therefore, the refracted image is upside-down when viewed through the drop. Somehow, bees, such as this bumblebee, figure out this hall of mirrors and are able to get to the daisies’ nectar. "
