To familiarise yourself with the soil outside where you are walking, you can carry out a simple sedimentation experiment. Place a few spoonfuls of soil in a glass of water and cover with a lid to form a cosmos. Stir first. Biological and geological materials will slightly colour the water inside the glass. The colours range from the blacks of soils to the greys of rocks. Mineral particles sink to the bottom and join together in different layers, determined by the density and porosity of each individual part. Light biological components swirl around. When the circles of water have subsided, they slowly settle and become weightless, floating silently. When you then later place your hand in the soils, let your fingers inscribe.
