Travelling Nutrients
Tweet Water is often called the Universal Solvent because it can dissolve more substances than any other liquid, often carrying these dissolved particles with it. When water travels through soil, nutrients (food) and dissolved particles travel with the water to be deposited somewhere else. Here is an experiment to visually demonstrate how this process happens. [...]
