## In authors' words

### What they set out to do (purpose)

Explore chemotaxis in water droplets.

### What they found (results)

Governed by molecular physics, these droplets behave in a chemotaxis-esque way, exhibiting behavior where they “choose” similarly colored droplets or or "attract" or “chase” other droplets.

## Commentary

### In short

The water droplets are Distinguishing between the other droplets to Perspectivaly organize themselves into larger droplets.

### In more detail

Even non-living material such as water droplets are able to use a form of chemotaxis. A Stanford biology and physics lab accidentally discovered odd behavior in droplets of water with food coloring in them. The droplets appeared to “sense” each other and would move in peculiar ways.

Governed by molecular physics, these droplets behave in a chemotaxis-esque way, exhibiting behavior where they “choose” similarly colored droplets or or "attract" or “chase” other droplets.

This occurs through various methods. For example, it occurs when droplets chemosense high or low energy and move accordingly across a gradient of surface energy. These water droplets are Distinguishing between the other droplets to Perspectivaly organize themselves into larger droplets.
