So, if necessary, I prefer to warn you against the temptation to attribute any will to the snow crystal: no, I assure you, it is not consciously stealing the droplets to grow at their expense!
In reality, this transfer of water molecules is a natural process called the Bergeron effect.

Once in action, it induces the gradual evaporation of the droplets, and the water vapor thus formed joins the crystal, freezing onto it in turn (it should be noted that
As you can see, water vapor plays a central role, not only in the formation but also in the development of the snow crystal. Almost everything depends on it.
If the crystal finds good quantities of them in its vicinity, it eventually becomes too heavy
