Terence Cosgrove is the tech chief at Revolymer, the company that created this chewing gum. The candy can be washed away pouring water on it with soap:
"Gum base is a very complex mixture involving interactions of several components which give rise to the adhesion of gum base to a variety of surfaces. Using our technology, we have managed to change the surface characteristics of the gum base which will allow a stream of water or a mild soap solution to break the adhesion between chewing gum residues and surfaces such as paving stones, furniture, hair etc' " explained Professor Terence Cosgrove Revolymer's Chief Scientific Officer.
