Gum Wall

You could call it local flavour, but you probably wouldn’t want to taste it. Seattle’s least likely tourist attraction, the so-called “Market Theatre Gum Wall” – a brick wall smothered in up to a million multi-coloured gobbets of chewed gum – is to be scrubbed clean for the first time in two decades.

Part interactive art exhibit, part public health hazard, the Gum Wall has become a danger to itself, as the sugar in the gum has reportedly begun to erode the bricks beneath.
