New technique developed by MIT researchers provides first direct views of how drops and bubbles adhere to surfaces -- and how they let go.
An illustration of the setup that MIT researchers used to image the tiny 'necks' that form where a droplet contacts a surface. The image at the bottom shows the base of an actual water droplet moving across the surface and was taken using a special scanning electron microscope.
