Splashing liquid paint or dye onto a surface is one of the most unpredictable and exciting means of applying colour. Take turns at the classroom sink, dipping whole sheets of paper into watered down acrylic, splashing and flicking water across your work: holding paper, canvas or other painting surfaces in the air and letting the paint run down. Once an appealing wash of colour has been achieved, placed the artwork flat to dry, so the paint or ink pools and dries in naturally occuring swirls.
