3 days in Switzerland 🇨🇭for the launch of the @firn.biotechnology solar line, featuring the magical panorama of the Jungfraujoch at 3475m, the Sphynx Observatory, the Ice Palace, and Europe’s highest railway ❄️🚞🧊
Ps : did you know that FIRN is the snow on the upper part of a glacier, where it has not yet been compressed into ice ?
