What do a wormhole in the universe and the Weltacker’s mobile “wormhole” have in common? Both open up access to a hidden world. But while one leads to distant galaxies, our wormhole opens our view downward—directly into the captivating universe of the soil.
Countless organisms live there—from springtails to fungal networks—that form the foundation of our food supply, our climate, and a healthy environment. Yet much of what happens in the soil remains invisible to us—and thus often goes unnoticed. This is exactly where our wormhole comes in: it makes the invisible visible, audible, and tangible.
With its playful exterior and scientifically grounded interior, it invites people of all ages to experience the soil with all their senses. The mobile tent brings microscopes, soundscapes, and “aha” moments to every corner of the city—and impressively demonstrates just how much life is teeming beneath our feet.
In October 2024, the loss of our beloved mobile wormhole hit us hard. After a successful season full of outdoor adventures across Berlin, it fell victim to the fire at the Ackerhaus. But now there’s good news: Thanks to the generous support of the Stiftung am Grunewald, we were able to build a new wormhole—and artist Marie Basten has once again lovingly designed it!
The Wormhole is at the heart of our educational project, “The Wormhole on the Move: Exploring Soil Biodiversity with Berliners of All Ages,” and helps people understand the soil as a fascinating and endangered ecosystem. It tours Berlin events and invites visitors to experience the soil with all their senses:
Whether at the Environment Festival, the Long Night of Science, or the Harvest Festival—the Wormhole captivates audiences with its playful yet scientifically sound approach to sharing knowledge and raises awareness of the importance of soil biodiversity in global agriculture.
If you'd like to experience the new Wurmloch in person, you can find it on these dates, for example:
Since 2022, the Weltacker Youth Council has been working with us—an exciting project that brings young people in Berlin together. They all share one goal: a voice in Berlin’s food policy!
