Captured Cloud

This exhibit is not accessible during the winter months.
To get up close to clouds, you usually have to go high up in the mountains. You can easily step into this cloud and experience what it feels like. How well do your orientation senses work in the cloud? The two half-shells also concentrate the sound. It suddenly sounds quite unusual when people clap or speak in this cloud.
