Sun Sensitive Paper
Make amazing white on blue prints with your favorite objects! Just place leaves, flowers, shells or whatever you choose on the photo-sensitive paper and place in the sun. Remove the objects after a couple of minutes and rinse the paper to “fix” it. Congratulations, you’ve made a permanent piece of sun art!
@WaterNinja82 It has something to do with the Iron salts that are in it, i think they react with water, i could be wrong.
does it turn color back when it's not in contact to the sun for a long time?
