This Seattle sidewalk art only appears when it rains

A Seattle artist is beautifying the city’s sidewalks with art that only becomes visible when the pavement gets wet, bringing a whimsical dimension to the city’s reputation for rainy weather.

Artist Peregrine Church developed a water-based, invisible spray that lasts up to four months and reveals designs when it gets wet, explains Maggie Penman in The Washington Post. 

Church now runs a company that sells the paint to other organizations. “Church has worked with schools and universities, such as Indiana University; nonprofits like the Kimball Arts Center in Park City, Utah; and public transit authorities and parks departments in Washington state to create fun distractions for people waiting for a bus or walking down the street on a dreary day. He’s made a maze near a bus stop, an environmental message in a park, an ode to rain on the sidewalk.”
