Printing on paper using only the sun? The greatest prints are created with this special Sonnendruck paper. To do this, simply place different objects such as leaves, flowers or puzzle pieces on the paper. This is then placed in the sun for some time and then placed in a water bath. It changes color and the print becomes visible.

But how can it be that you can only print with the help of the sun's rays? The paper is coated with ferrous powder on the darker side. Sunlight turns it into a blue dye.
