While these reptiles rarely let their prey escape, Agathe, David, and Vincent wonder if it’s really possible to outrun a crocodile.

Agathe, David, and Vincent are heading back to the Middle Ages! Our test subjects are going to put the armor’s durability and maneuverability to the test.

Whether we’re high up on mountain peaks or deep in the oceans, our bodies don’t react the same way. To test the limits of the human body, Agathe and David put Vincent to the test.

Our testers aren't afraid of anything. They bring a five-meter-long python into the hangar. How do you distract a python? Agathe, David, and Vincent are going to put the predator's reflexes to the test with a series of challenges.

It was a historical event dating back to 1850 that inspired Agathe, David, and Vincent to undertake this new experiment. Napoleonic soldiers are said to have destroyed the Angers Bridge by marching across it.

Top-level rowers and a barefoot champion will be invaluable allies in tackling this challenge. What speed should they maintain? How many rowers should they recruit? What type of ski should they choose?

Our test subjects are going to achieve the impossible: living on Earth just as they would in space. Vincent heads to Cologne to the European Space Agency to undergo intensive training with top astronauts.

Our test subjects are going to peel bananas to analyze their skins. Are they really slippery? To find out, we’re conducting large-scale tests in the lab, including a race through hundreds of banana peels.

Vincent, James, and David find themselves stuck in traffic, trying to see if the lane next to them is moving any faster.

Our dynamic trio is going to make many schoolchildren’s dream come true: building a giant paper airplane. Vincent takes to the skies in a glider to study aerodynamics and takeoff techniques.

Will Agathe, David, or Vincent come up with the best glue to stick Vincent to the ceiling? Everyone has their own recipe, but there’s only one rule: the mixture must be natural.

Off to the Calanques of Marseille, where a perilous mission awaits Vincent. Agathe, intrigued by the methods of an extraordinary spider, has set him a challenge: just like the spider, he’ll have to try eating underwater.

Our test subjects’ imaginations know no bounds: they’re defying the laws of gravity to send Mini-James into space.

Our dynamic trio tackles another common misconception: Are bats really so blind and clumsy that they get tangled up in people’s hair?
