Einstein Year Award: 1st Prize
by Robert Anderson
The surface tension of water can support even a metal paperclip. By photographing it using a grill in front of the light source, the deformation of the water caused by the clip's weight can be seen. This bending of light is similar to the bending of light by strong gravitational fields, as predicted by Einstein's theories. Surface tension is due to an attraction between the molecules in water, which cause its surface to act in an elastic manner.
