Snowflake unlikely that any two snowflakes are alike due to the estimated 10 (10 quintillion) water molecules which make up a typical snowflake, which grow at different rates and in different patterns depending on the changing temperature and humidity within the atmosphere that the snowflake falls through on its way to the ground. Snowflakes that look identical, but may vary at the molecular level, have been grown under controlled conditions. Although snowflakes are never completely symmetrical, a non-aggregated snowflake often grows so as to exhibit an approximation of six-fold radial symmetry. The symmetry gets started due to the hexagonal crystalline structure
Cue stick are stained, translucent, transparent or painted. These cues are also valued because of how well they perform. Competitors of custom cue makers and mass-production manufacturers usually try to make cues look like they are made of expensive materials by using overlays and decals. Although these lower the cost of the cues, they do not degrade the cues' effectiveness in game play. Another mark of quality is the precision with which inlays are set. High quality inlays fit perfectly with no gaps; they are symmetrical on all sides, as well as cut cleanly so that all edges and points are sharp,
