Vanishing spray, also known as magic spray or foam spray, is a tool used in football matches to mark temporary lines on the pitch for free kicks and walls. The purpose of this spray is to ensure that the defending team maintains the right distance from the ball and the attacking team does not gain any unfair advantage. There are various alternatives to vanishing spray that can be used such as line marking paint, chalk powder, or even a simple measuring tape. However, vanishing spray has become the preferred choice due to its convenience, accuracy, and ability to disappear into thin air within a minute.
