Definition & Meaning of "vanishing spray"

What is "vanishing spray"?

Vanishing spray is a type of spray used in sports, especially soccer, to temporarily mark lines or positions on the field. It creates a short-lived, visible mark that disappears after a few minutes, helping referees and players see where to position themselves for free kicks or other planned plays. The spray is usually made from a foam or liquid that evaporates quickly, leaving no permanent marks.
