Perfect Sphere
Reflections in a rolling ball fountain in Bad Dürkheim. A perfect sphere of blue Brazilian quartzite, floating in a corresponding socket in a pressurised stream of water. The marble is covered with a thin film of water that provides reflections like this one. The stone has a diameter of 1.25 m and weighs 2.2 tons, but the direction of rotation can be changed with the greatest of ease.
And while we're on the subject of blue and Bad Dürkheim, this is the town where Gustav Kirchhoff and Robert Bunsen (of burner fame) discovered the atom caesium (Lat. "sky blue"). During spectral analysis experiments they encountered unexpected blue lines in the emission spectrum, which led to the discovery of the new atom. To isolate 7.3 g of caesium chloride they needed 44,000 litres of Bad Dürkheim mineral water.
