It's like having your own solar darkroom...without the dark part. This kit includes special light sensitive paper that allows you to make unique designs using only sunlight and water. Simply place an assortment of interesting objects on the paper while you're indoors. You can use the included acrylic sheet to hold flat objects in place. Then simply take the paper outside and expose it to sunlight for a few minutes. Rinse the paper in water and you get a fascinating image of the objects on the paper. Perfect for leaning about transparent, translucent, and opaque objects. You can even place photographic negatives on the paper and transfer the image. And you can also feel good about buying our sun print paper because it has the smallest carbon footprint of any sun print paper on the market. Kit includes 15 sheets of paper, 5X7 inch (12.5 X 18 cm.) and 1 acrylic sheet. For ages 6 and up.
