Explaining The Universe on Instagram: "A three-dimensional soft cell for holding liquid in space is a flexible, membrane-like container that relies on surface tension and capillary forces rather than gravity to keep fluids in place. In microgravity, liquids naturally form spheres and drift, so the soft cell’s curved walls, internal channels, and elastic structure guide the liquid and prevent it from breaking into floating droplets. As the membrane gently flexes, it helps reposition the fluid and
