Seattle-based artist Peregrine Church has a unique take on street art. Using stencils and a superhydrophobic spray (such as Always Dry), he creates what he calls rain art, art that only appears when it rains. As he sees it, Seattle is the perfect place for such art, a way of revealing a world of art and “chin up” messaging for the city’s all-too-frequent rainy days.
How it works couldn’t be simpler. He lays down a stencil, sprays the liquid, and then waits for rain for the big reveal. When the area gets wet, since superhydrophobic sprays resist the water, everything around it gets wet, thereby exposing the art. When the rain subsides, the art goes back into hiding. It’s like urban invisible ink.
