In 2021, the Museum of Natural History in Neuchâtel opened its new semi-permanent exhibition dedicated to Lake Neuchâtel. I made the film explaining how the lake is stirred up (a phenomenon known as “brassage du lac in French”.

Film content

The film explains how the lake’s waters are mixed by the wind. This mixing is a physical phenomenon that is very important for the lake’s biodiversity. In summer, the water in the lake forms strata: the water heated by the sun stays on the surface and the colder, denser water sinks. The strata, which contain different concentrations of oxygen and nutrients, do not mix. With the falling temperatures in automn and the winter winds, these strata mix. The bottom of the lake is oxygenated again.

An interactive movie

In the “winter” part of the film, it is the visitor who triggers the stirring of the lake. They are invited to blow on the video to stir up the lake. The rest of the video is triggered by a sensor installed next to the screen. I made the film myself, but the technical installation was provided by the Museum of Natural History in Neuchâtel.

A successful collaboration with Neuchâtel’s Museum of Natural History!

I’ve had the opportunity to work for the Museum of Natural History in Neuchâtel on several occasions. The first exhibition was “Manger, la mécanique du ventre”, for which I set pre-existing graphics in motion. I then made a film for the ‘Pôles, feu la glace’ exhibition, explaining the Milankovitch cycles , and an interactive game for the ‘Sauvages’ exhibition in 2022, among others.

A Christmas clip on the theme

Unfortunately, I can’t show the film about the brewing of the lake here, but below you’ll find a clip on the same theme. The Museum de Neuchâtel often produces end-of-year greetings clips for social networks. These are usually linked to current exhibitions. I had the opportunity to make several of them. Naturally, the theme that year was the brewing of the lake:
