A snowball is a ball of snow, usually created by scooping snow with the hands and compacting it into a roughly fist-sized ball. The snowball is necessary to hold a snowball fight. The pressure exerted by the hands on the snow is determinant for the final result. Reduced pressure leads to a light and soft snowball. A higher pressure cause the snow to melt, turning into liquid water. Once the pressure is removed, the water turns again into ice, leading to a more compact and hard snowball, which eventually can be considered harmful during a snowball fight.

A snowball may also refer to a large ball of snow formed by rolling a smaller snowball on a snow-covered surface. The smaller snowball grows by picking up additional snow as it rolls. The term snowball effect is named after this process.
