5th Place – The Salty Night, Nick Sather

The "waves" in this image are the edge of a 3D-printed hydrogel. Hydrogels are made of water, but act like soft solids such as jelly, contact lenses, or cartilage in our joints. The "stars" here are salt crystals. These help solidify the hydrogel. By forming a flexible, jelly-like material, these hydrogels can be 3D-printed into any shape. For example, we can print hydrogel implants to heal damaged cartilage in human joints.
