Gravity Liquid 21Edition 1 5 In his Gravity Liquid series, Janiak creates visual representations of the idea that form cannot exist without an environment. There are the visible forms we see in the world, and then there are the conditions that allow those forms to exist. As a catalyst for his exploration of this topic, Janiak chose gravity, one of the most ubiquitous and easily observable forces, and the one that allows so many forms in the physical universe to exist.
