Researchers from Bristol University have created a non-stick chewing gum.

The gum contains two polymers which have opposing properties - one repels water and the other attracts it. The result is a gum that won’t stick when it is wet or dry.

Professor Terry Cosgrove, who developed the gum, said that the invention was still at a very early stage: “What we have is the base for chewing gum without any of the flavourings or other ingredients.”
