Cyanotype Process and Techniques

Mr. Brown and Squeaks return from a nature walk and explore the concept of sun prints, also known as cyanotypes. Mr. Brown explains the history of cyanotypes, highlighting Sir John Herschel's discovery and Anna Atkins' contributions. He demonstrates how to create a cyanotype using special paper, leaves, and sunlight. The science behind the process involves a chemical reaction that produces Prussian blue, a dye that remains after rinsing. The video concludes with a call to action to subscribe to SciShow Kids.
