Chewing gum that doesn't stick invented by British university

Easy-to-remove chewing gum is to become a reality, thanks to a breakthrough by chemists that could save Britain the £150 million spent every year on removing discarded gum.

The British start-up company that announces the non-stick, degradeable gum today hopes to take a bite of a global market worth £5 billion, of which Britons alone spend £325 million annually.
