>This article is about the art form. Drawing also refers to a method of producing wire, bars, or tubes. Drawing is a means of making an image, using any of a wide variety of tools and techniques. It generally involves making marks on a surface by applying pressure from a tool, or moving a tool across a surface. Common tools are graphite pencils, pen and ink, inked brushes, wax color pencils, crayons, charcoals, pastels, and markers. Digital tools which simulate the effects of these are also used. The main techniques used in drawing are: line drawing, hatching, crosshatching, random hatching, scribbling, stippling, and blending.

Ball wiki:
>For other uses, see Ball (disambiguation). A ball is a round object that is used most often in sports and games. Balls are usually hollow and spherical but can be other shapes, such as ovoid (only in a few special cases) or solid (as in billiards) and flat (as in ice hockey). In most games using balls, the play of the game follows the state of the ball as it is hit, kicked, or thrown by players.
