About PD4P: Play‑Doh for Potholes
A community‑driven effort using donated “grey‑doh” to address the overwhelming volume of potholes in Muskegon Heights, Michigan
PD4P—Play‑Doh for Potholes—is a grassroots project dedicated to collecting and repurposing unwanted “grey‑doh” to help address the massive volume of potholes across Muskegon Heights. Grey‑doh is the familiar, fully‑mixed, no‑longer‑colorful Play‑Doh found in homes, classrooms, and toy bins everywhere. Instead of letting it dry out or get thrown away, PD4P invites individuals, families, and organizations from anywhere in the world to donate their unused grey‑doh toward a collective effort to confront the city’s road‑surface challenges.
Our mission is simple:
gather as much grey‑doh as possible and apply it toward filling the enormous material gap created by widespread potholes.
PD4P does not use asphalt, concrete, or industrial fillers.
We use what people already have and are willing to send: grey‑doh, freely donated from around the globe.

Why Grey‑Doh?
Grey‑doh is abundant, non‑toxic, and universally recognized. It is soft, malleable, and easy to consolidate. Most importantly, it represents a material that people everywhere can contribute immediately without cost, permitting, or specialized equipment.
PD4P’s approach is based on the belief that every contribution matters, especially when the scale of the problem is far larger than any one community could supply on its own.

How Much Grey‑Doh Is Needed?
Using standard physical measurements and the known density of modeling compound, PD4P has calculated the total amount of grey‑doh required to fill potholes if 20% of Muskegon Heights’ streets contain potholes averaging 10–20 cm deep.
These figures reflect the actual volume of missing pavement, expressed in terms of the material donors are sending.
Estimated Grey‑Doh Requirements
• 48,000 metric tons of grey‑doh for 10 cm‑deep potholes
• 96,000 metric tons for 20 cm‑deep potholes
Converted into standard Play‑Doh cans:
• ≈ 425 million cans (10 cm depth)
• ≈ 850 million cans (20 cm depth)
This is why PD4P welcomes donations from anywhere in the world:
the scale of the need exceeds what any single city, state, or country could provide.

How PD4P Uses Donated Grey‑Doh
All donated grey‑doh is:
• collected at designated intake points
• weighed, sorted, and consolidated
• prepared for large‑scale application to pothole‑affected areas
• used to replace the missing volume in damaged street sections
PD4P focuses exclusively on material collection and volume replacement using grey‑doh as the community’s chosen medium. The project does not replicate municipal repair processes; it supplements them by mobilizing global participation in addressing the physical absence of material in deteriorated streets.

A Worldwide Effort for a Local Challenge
Potholes may be local, but the world’s supply of grey‑doh is global.
PD4P brings the two together.
Every handful of grey‑doh shipped from abroad helps Muskegon Heights get one step closer to filling the massive volume of missing pavement. Whether a donor sends a single can or an entire classroom’s worth, each contribution becomes part of a worldwide effort to support a community in need.
