Why is it wrong to call it “artificial snow”?

In the same way as natural snow, machine made snow consists exclusively of the elements water and air. The only difference is that machine made snow is produced by a machine. It is therefore incorrect to talk of “synthetic snow”. Synthetic snow is in fact plastic or polystyrene snow made for the theater or films. The correct term for snow made from snow-making equipment is “machine made snow” or “man made snow”.
