You how a snowflake looks like that? It is made of ice but it is structure with gaps in it. When the snowflakes are in large clumps there is tons of air even as they rest on top of each other. If you have air inside ice it has a white colour so the white of snow is the air and ice interacting. It isn’t one solid mass that can be seen through but rather you “see through” part of the ice of a snowflake just to see another bit of the snowflake or another flake entirely.
The fluffyness is again a property of the air space between the ice. The more you compact snow the more it begins to have the qualities of ice but it needs to melt and then refreeze entirely for 100% of the air to be removed and become one solid crystal as opposed to lots of crystals mushed together. Sand and glass is similar.
