During the 30 minutes presentation, you will be challenged by the unusual nature of the experiments, explosions, instantaneous evaporation, fog which is dry to the touch, the whole family will find something for everyone from 5 years old!

200 million years of martian history in a tube

What happened to the ocean that would have existed in the first million years of Martian history? How was the atmosphere of Mars when the planet was formed? The primitive history of Mars is replayed in a few seconds in a simple tube and you will be able to witness with your own eyes the phenomenon of evaporation of the oceans and formation of an ice cap which occurred on Mars a few billion years ago.

Weather in the palm of your hand

At the end of the presentation, a presenter will allow you, if you dare, to hold in your hand a small corner of the Martian atmosphere, reproducing one of the most spectacular weather phenomena on Mars: a freezing fog whose temperature drops to -65°C.
