Two Coloured Flower
Dilute red and green fountain pen inks with water
and fill two glass tubes each with one colour. Split
the stem of a flower with white petals, e.g. a dahlia,
rose or carnation, and place one end in each tube.
The fine veins of the plant soon become coloured,
and after several hours the flower is half red and
The coloured liquid rises through the hair fine channels by which, the water and food are transported.
The dye is stored in the petals while most of the water is again given off.
