Bertille's cabin is on fire. Olive invents a reciprocating pump because using mammoths to put out fires is not very functional.

The islanders try to find the most efficient way to milk the mammoths. After several attempts to lift the mammoths, Olive and Franck create a system of double pulleys to facilitate changes in direction, speed and force for lifting the animals. You will discover the very first mammoth milk production plant, not to mention the very…

Because mealtime causes huge traffic jams, the islanders come up with an ingenious plan to build a new road. During construction, they discover all sorts of uses for inclined planes to facilitate the movement of people and equipment. In this episode, the islanders uncover the principle of one of the first machines ever invented, the…

The islanders are experimenting with the principle of buoyancy. When an object is placed in water, its volume will displace the water, which in turn pushes the object away. If the force of buoyancy is equal to the weight of the object, the object floats.

The date of the big contest for the heaviest mammoth is approaching. Olive uses her creativity to find solutions to weigh the mammoths, using a complex system of levers to make the task easier.

Because of the summer heat, the mammoths give off a stench. To remedy this, the islanders try to wash them. Based on the principles of wheels and axles, Franck, Barnabé and Olive make several attempts to build machines to dry the mammoths.

To meet the delivery deadlines for her aunt's pizza store, Olive designs a series of engines and rockets for the delivery mammoths.

Bertille is trapped in the tower. On the advice of Olive and the inventor, the villagers build a ramp around the tower and turn it into a giant screw to free Bertille. What ingenuity!

Each year, the inhabitants of the island prepare a big fun fair. But this summer, Olive decides that the party must be really successful. The inhabitants of the island set up a fabulous merry-go-round, combining a swing and a series of gears. This simple machine makes it easy to change direction, speed and force.

Our island experts explain that when light rays penetrate transparent materials, they are refracted or diverted. Light rays from a distant object are deflected by the lens and converge on a surface. The light rays, coming from the top and bottom of the object, are inverted and the image they form is reversed. This episode is about the…

Franck and Barnabas discover that when they attach a blind to the back of a delivery mammoth, it flies away, pushed by the wind. They review the properties of air and the four forces of flight to modify their invention.

Even on the island of the mammoths, misfortune happens quickly. One sunny day, the bridge leading to the island of pastures suddenly collapses, leaving Barnabas and his herd stranded on the other side! Fortunately, the inhabitants of the island soon build a boat based on the principles of the magnetic field that will bring the…

The discovery of steam engines opens new perspectives for the inhabitants of the island in search of speed and strong sensations.

The weather is freezing on Mammoth Island, and a hot bath would be a comfort to the inventor, but all the water pipes are frozen. Frank and Barnabas set up an ingenious 'mammoth-calorific' shower system. The system only works if the mammoth is not awakened.
