Question

What object is shown in this zoomed-in close-up photo?

PixelLynx · Accepted Answer

Vodka bottle glass texture (macro). Vodka is defined mainly by what it lacks rather than what it contains; by law in many countries it must be nearly flavourless and colourless, distilled to a high purity that removes most of the congeners found in other spirits.
