Taking the stick out of a stick of gum. I’m Bob Hirshon and this is Science Update.
A chewing gum that won’t stick to shoes, hair, or pavement may soon be coming to a store near you. It’s made by a British company called Revolymer, spun off from the University of Bristol. CEO Roger Pettman says they’ve replaced sticky ingredients found in regular gum with a polymer that easily detaches from surfaces. They’ve field-tested it on a number of surfaces, including real city sidewalks.
ROGER PETTMAN (Revolymer):
As soon as it rains, our chewing gum is simply washed away. And in three out of four cases, the commercial gums just remained there.
They also found that the gum actually dissolves in water over several weeks – which may curb the impact of chewing gum litter. Pending government approval, they hope to start selling the gum in Europe and the United States within a year. I’m Bob Hirshon, for AAAS, the science society.
