## Acid Ball, Waypoint Park (Bellingham, WA): What It Is, How to See It, and Why It Matters

The Acid Ball is the spherical centerpiece of Waypoint Park on Bellingham’s waterfront—a rescued industrial artifact turned public art. In 2018, the City of Bellingham coated the 1930s-era steel vessel with thousands of reflective glass beads, creating a night-friendly installation that responds dramatically to light and anchors the city’s redeveloped shoreline. of Bellingham

### What exactly is the “Acid Ball”?

– Original purpose (c. 1938): An industrial relief system for the waterfront pulp mill. It drew liquid and gas from the digester tanks (“rocket ships”) to maintain constant pressure while wood chips were cooked at high temperatures. of Bellingham
– Scale: About 32 feet in diameter and over 430,000 pounds; moved 1,000+ feet from its original spot to the water’s edge during park construction. of Bellingham

### The design move (and why it works)

The city selected Mutuus Studio’s “smallest big move” approach: keep the artifact intact and add a traffic-bead style reflective skin. The result honors the site’s working-waterfront history without erasing patina or form—and it creates an interactive piece that glows under headlights, bike lights, or handheld beams. It’s a rare case where industrial salvage becomes a nighttime landmark with almost no added mass. STUDIO
