For an ongoing project entitled Rainworks, Seattle-based artist Peregrine Church creates awesome works of street art that are only visible when it rains. It’s a particularly wonderful concept for a city renowned for its rainy weather Church uses a superhydrophobic coating to stencil images onto ordinary pavement. On a dry day the pieces are completely invisible, but when the surface gets wet, darkening the untreated concrete, the treated areas repel the moisture, which causes the stenciled images and/or text to appear. Depending on the amount of foot traffic the treated surface receives, Rainworks will last anywhere from 4 months to a year.
Watch this video to learn more about how Peregrine Church creates his dissapearing-reappearing artwork.
Want to try making Rainworks of your own? There are a variety of superhydrophobic coatings currently available, including a handy kit by Rust-Oleum.
