# unstable (condition)

drift accelerates toward a wall on its own

- Computed level: L15 (depth in the emergence graph, not abstraction)
- Status: review  ·  Domain: emergent  ·  Arena: system

## Emergence
**Emerges from:** [drift](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-drift.aimless), [wall](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-wall.range-end), [toward](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-toward.spatial)

**Through:** The unguided change intensifies in the direction of a boundary.

**Novel properties:**
- self-intensifying drift
- directed acceleration
- proximity-driven change

## Examples
- The Tacoma Narrows Bridge oscillated wildly in 42 mph winds before collapsing on November 7, 1940. *(engineering)*
- A spinning ice skater wobbles uncontrollably when angular momentum shifts beyond balance. *(physics)*
- The 2008 financial crisis accelerated as mortgage defaults fed cascading bank failures. *(economics)*
