Maze
Plant a sprouting potato in moist soil in a pot. Place it in
the corner of a shoebox and cut a hole in the opposite
side. Inside stick two partitions, so that a small gap is
left. Close the box and place it in a window. After a
couple of days the shoot has found its way through the
dark maze to the light.
Plants have light sensitive cells, which guide the direction of growth. Even the minimum amount of
light entering the box causes the shoot to bend. It looks quite white, because the important green
colouring material, chlorophyll, necessary for healthy growth, cannot be formed in the dark.
