New spray invented that accurately detects lead

[gengar]

A new spray has been developed in The Netherlands that accurately detects lead in objects. By spraying it on an object, it glows green when there is lead present. It's not commercially available and there is not many info on it yet, but it exists. Look it up if you're interested.
