Neutrinos, also known as ghost particles, are abundant but minuscule and extremely hard to detect. Tens of trillions of neutrinos from the sun stream through your body every second, but you can’t feel them. Geist by This Is Loop at Canary Wharf’s Winter Lights Festival 2026 is inspired by neutrino detector equipment and uses neutrino oscillation measurements from the T2K neutrino experiment in Japan. It explores the work taking place to trace neutrinos and asks what these tiny particles might reveal about the universe. Inspired by enormous neutrino detectors, Geist (from the German word for “ghost”) is an exploration of the complex game of ‘hide and seek’ that Japanese scientists play to find and provide evidence for the existence of these particles. See it at Union Square from 20–31 January, then pop by Marugame Canary Wharf for a warming bowl of noodles. Directions here.
