A new machine created by Chris Beauvois is able to grow plants without water in soil. The machine does this by trapping a plant in a box that is filled with a nutrient rich, water-based mist.
Just about everyone who has had a grade school science class is familiar with hydroponics. Take just water and put a small plant in it and greenery will grow without soil. I have carrot top and various other plants in just water. I even started an avocado tree.
