Peppermint Pointillist chewing gum displays Chewing gum displays encourage people to use their chewed gum to create art that reveals messages about the issue of litter. Did you know that the average piece of chewing gum costs 3p to buy and £1.50 to remove? To help us solve this sticky issue we installed some Peppermint Pointillist displays on Villiers Street. The displays highlight the cost of clearing up chewing gum and the amount discarded on the streets using creative artwork.
