The paper undergoes a chemical change when exposed to sunlight. Save the print by soaking in water then drying. The Solar Imaging paper can be used for a creative, solar art project. With this paper you can also demonstrate UV blocking sunscreen by smearing sunscreen on plexiglass and exposing the paper to the sun. Use different strengths of sunscreen and see how the image has changed. These kits use the energy of sunlight and water to create a shadow print on 5" x 7" sun-sensitive paper. Natural objects like flowers, leaves, shells or some man-made objects are all you need to make beautiful and unique prints. You can also use old negatives for a unique project! Make several images in different sizes, single frame each or use a collage frame and display a wall of creativity at home or school. Kit includes 12 - 5 x 7 sheets of solar paper, instructions, practice paper and 3 cowboy themed silhouettes.
