I really love doing this particular activity with the kids during the spring season. It gives us the opportunity to explore the chemical reaction that occurs when the sun is involved. You can find this unique paper, designed for creating images with various objects and sunlight, at your nearby store and online.
To begin, place the item(s) on the paper and let it soak up the sunlight for around 1-2 minutes. You can select various items like leaves, flower petals, grass blades, and sticks. As soon as the parts of the paper exposed to the sun turn white, signifying the end of the solar printing procedure, the section under your object will stay blue since it was not exposed to the sunlight. Afterward, remove the paper from sunlight and eliminate the objects. Rinse the paper with water and let it dry.
