Phil's photos with the keyword: Glass

Just a snapshot of a pair of crystal dolphins in a glass sphere....it took quite a few attempts to get the focus right and the reflections in the right place. Camera: Nikon D300s Lens: AF-S DX Zoom-Nikkor 17-55mm f/2.8G IF-ED Processed with Nikon Capture NX2.

A Galileo thermometer (or Galilean thermometer) is a thermometer made of a sealed glass cylinder containing a clear liquid and several glass vessels of varying mass. As the temperature changes, the individual floats rise or fall in proportion to their respective weights and the density of the surrounding liquid. It is named after Galileo Galilei because he discovered the principle on which this thermometer is based—that the density of a liquid changes in proportion to its temperature. (Wikipedia).
