The children were told to put on plastic gloves to help wash the fabric used for the Cyanotype technique by artist Ya Chu Kang. To do the Cyanotype she had the children put their hands on the material along with their favorite toys. Once the material is exposed to the sun it turns blue. The material that was protected by the children’s hands or toys remained white. Her project was part of the Cheng Long Wetlands International Environmental Art Project in Taiwan.
