Years of research and trial and error culminated in the invention of the first locomotive on rails. Not bad for a father-and-son experiment. That's what Murdoch and his son George achieved in 1797.

George Stephenson tries out his invention, a steam locomotive. He allows his son, Robert, to ride on it as long as he stays on the edge of the carriage and gets ready to jump off if the rails buckle under the weight of the locomotive... which they do. Luckily his son followed his instructions!

In a convivial atmosphere, complete with brass bands and good humor, Parisians gather in the streets to have fun and raise awareness about the proliferation of electronic adverstising in the subways. A new citizen movement is spreading throughout France: anyone can join the ranks of "Les Reposeurs" [Redecorators], a group of protesters armed with kraft paper, markers, and whiteboard paint to write anti-advertising messages on posters and billboards.

The future of the railroad depends on whether George Stephenson's locomotive, 38 cars long, will run or not. The local townspeople debate whether it will go full speed ahead or not budge at all due to its size.

This next part of the Il était une fois series on George Stephenson deals with the Rainhill Trials, a competition that determined what kind of trains (steam engines or locomotives) would be used on the Liverpool and Manchester Railway.

This last part of the Il était une fois episode on George Stephenson deals with the Rainhill Trials, a competition that determined what kind of trains (steam engines or locomotives) would be used on the Liverpool and Manchester Railway. Stephenson proves to be the best competitor.

Meet Sheldon, the friendly robot with friendly eyes that flash little hearts when it interacts with people. Sheldon is a huge attraction at tech fairs, where it is used to entertain and delight the crowds. It certainly lives up to the task.

In "Éducation Nationale," the slam poet Grand Corps Malade gives us his opinion on the shortcomings of the French national education system through the eyes of Moussa, a fifth grader in Épinay. It's a touching song and a call for change in the name of equal opportunity.

In an effort to promote ecotourism, the town of Echelles has constructed one of the largest natural bathing areas in France. Its filtration system is 100% natural, powered by thousands of plant seedlings.

The Underwater Museum of Lorient might be a little hard to get to, given that it's literally underwater. Dedicated to shipwrecks and other sunken objects, the museum is made possible by a team of volunteers with a passion for documenting these lost treasures at the bottom of the ocean.

Lionel tells us about the Seine's recent flooding, caused by severe weather conditions in Paris and surrounding areas. A statue of a French soldier below the Pont de l'Alma acts as an indicator of the river's water level.

Parisians can thank Fulgence Bienvenüe for their metro system, which is so efficient that many people use the names of the metro stations in favor of street names when giving directions. Some of the most interesting stations are Bir-Hakeim, overlooking the Eiffel Tower, and Arts et Métiers, with its old-fashioned industrial design. Some metro stations are a destination in themselves!

Global warming is threatening the ski industry in the French Alps. Many operators have to resort to snow guns to keep the slopes open as snowfall has halved in the last fifty years.

Lionel and his cousin Jean-Pierre visit a nature park in the Saulnois region with some interesting wildlife. Storks are a major attraction in the region. Unlike other storks, these storks don't migrate, but stay year-round.

Lionel and Jean-Pierre try to find their bearings along the Lindre pond. Luckily they have a compass! Jean-Pierre will teach you how to use a compass and explain the difference between true north and magnetic north.
