This small 4.75" square Sunprint kit makes photographic type prints using the sun and water. The patented paper goes through a chemical change when exposed to light. You select an object from either the house (key, marble) or something from nature (leaf, flower), assemble the Sunprint kit items as directed, expose to the sun until the paper turns almost white (from 1 -5 min), and quickly rinse the Sunprint paper with water and dry. Voila - a work of art! The kit includes (12) 4" x 4" sheets of Sunprint paper and (1) 4" x 4" acrylic sheet.
