This magical activity is based on a photographic process: cyanotype. The child creates scenes on photosensitive paper using opaque patterns. When exposed to sunlight, a negative of the patterns is produced on the paper. Then, all that’s left to do is rinse the paper in a clean water bath and watch as the creations appear on the blue background!
With 4 felt-tip pens to transform 4 pictures into colourful underwater scenes.
8 sheets of photosensitive paper (21 x 28 cm), around 100 patterns printed on plastic, 1 sheet of plexiglass and 4 coloured felt-tip pens.
suitable for age 7 -99 years.
