This is a red and white paintball shot in very early explosion.  You can tell because
there is very little paint exuding from the paintball.  This picture is unique in that
it captured the paintball at almost the exact second that it burst open, and the
paintball still seems to be against the Plexiglas wall.  Another quality of the
picture that enhances it, is the slight reflection seen in the black Plexiglass.
