Taste the soil: London’s Museum of Edible Earth invites visitors to eat dirt from around the world

At first glance, it sounds like a stunt, but in central London, visitors are being invited to do something surprisingly rooted in human history: taste soil. The Museum of Edible Earth, currently on display at Somerset House, brings together edible earth samples from across the globe and turns them into a sensory, educational experience.

Far from a gimmick, the exhibition explores geophagy, the practice of eating soil, through science, anthropology and art. By combining tasting sessions with research-backed context, it challenges modern assumptions about what is considered food and opens up a deeper conversation about humanity’s relationship with the Earth.

What is the Museum of Edible Earth

The Museum of Edible Earth is an interdisciplinary project created by artist and researcher masharu.

It features a growing archive of more than 600 edible soil samples collected from over 40 countries, each documented with cultural, historical and chemical context.Rather than presenting soil as something strange or taboo, the exhibition treats it as a material with meaning. Visitors encounter soil not just visually, but through smell, texture and taste, turning the exhibition into a fully immersive experience that blends art installation with scientific inquiry.

The global history of eating earth

Eating soil may seem unusual in modern urban settings, but geophagy has been practiced for centuries across Africa, South America, Asia and parts of Europe. Anthropologists have documented its use in traditional medicine to soothe digestive issues, as a source of minerals such as iron and calcium, and in cultural rituals or pregnancy-related cravings.In some regions, specially prepared clay is even sold in markets as a consumable product.

The exhibition highlights these traditions to show that soil consumption is not a fringe behaviour, but a culturally embedded practice with historical depth.

What does soil actually taste like?

One of the most intriguing aspects of the exhibition is how it reframes soil as a sensory experience. Different types of earth offer distinct flavour profiles. Clay can taste smooth and slightly metallic, chalky soils may feel dry and mineral-heavy, and volcanic earth can have a smoky or earthy depth.Each sample is accompanied by tasting notes, similar to those used for wine or coffee, encouraging visitors to engage with soil in a structured and thoughtful way.Scientific research has explored why humans and animals consume soil. Some explanations suggest that certain clays provide essential nutrients, while others may help bind toxins and pathogens in the digestive system. Soil can also act as a protective layer against irritants in the gut.However, scientists caution that not all soil is safe. Contaminants such as heavy metals, bacteria and parasites can pose risks, which is why the exhibition uses carefully sourced and prepared samples.

Is it safe to eat soil?

The organisers stress that the tasting experience is controlled and optional. Visitors are guided through the process, and the soils provided are selected with safety in mind.That said, health experts do not recommend eating soil casually outside such curated settings.

The exhibition is intended to educate and provoke thought, not to encourage everyday consumption.

A living archive of human experience

One of the most unique elements of the exhibition is its participatory nature. Visitors are invited to leave their own tasting notes and reactions, contributing to an evolving archive of how people perceive soil.This transforms the exhibition into a collaborative project where science, culture and personal experience intersect, building a broader understanding of how humans relate to something as fundamental as the ground beneath their feet.

Sustainability and environmental reflection

The exhibition also carries a strong environmental message. Many of its elements are made using recycled materials, including compost derived from previous installations and organic waste.By focusing on soil, the exhibition draws attention to the foundation of ecosystems and agriculture. It encourages visitors to think about soil not as dirt, but as a vital resource that supports life, food systems and environmental balance.The idea of eating soil has sparked widespread curiosity online, driving conversations across social media. While the shock factor draws people in, the deeper appeal lies in the exhibition’s ability to connect science, culture and everyday experience.It challenges deeply ingrained ideas about cleanliness, food and nature, making visitors question assumptions they may never have considered before.The Museum of Edible Earth is more than an unusual attraction. It is a thoughtful exploration of history, science and sustainability that uses a simple yet provocative idea to engage audiences. By inviting people to taste soil, it turns an overlooked material into a powerful lens through which to examine culture, health and humanity’s connection to the planet.
