La répartition des forces

What is inertia? Daniel explains how this scientific principle is responsible for some messes! In his lab, Yannick is trying to pull a tablecloth over a table without knocking over the objects on it. Do you think he'll succeed without causing

Today, Daniel and Yannick show us the true powers of lasers. Do you think it's possible to light a match or pop birthday balloons using only laser light?

Do you know the difference between fluorescence and phosphorescence? Yannick introduces us to some very surprising fluorescent objects, like the banana!

Daniel explains what static electricity is. Yannick then uses this electrical phenomenon to perform all sorts of surprising and amusing experiments.

Daniel takes us on a tour of plastics. Did you know that adding lemon juice to milk produces a plastic? In his lab, Yannick uses chemistry to make nylon thread before our very eyes.

What do vinegar and lemon juice have in common? They're both acids. Yannick introduces Daniel to even stronger acids than vinegar and lemon juice. You'll be amazed at what they can dissolve.

How do hand warmers generate heat? Chemistry! In his lab, Yannick shows Daniel some surprising ways of producing heat

Keep your ears wide open, because we're interested in sound. With Daniel, you'll discover how a sound tube works. In his lab, Yannick produces sounds in surprising ways.

Do you know the action-reaction principle? It makes it possible to propel different objects at high speed. In his lab, Yannick uses the action-reaction principle to achieve a spectacular take-off.

Did you know that mirrors often play tricks on us? To prove it, Yannick presents Daniel with three amusing mirror challenges.

In this episode, Daniel introduces the notion of equilibrium. In his lab, Yannick modifies the center of gravity of a water bottle. Daniel then performs a magic trick to shift a spectator's center of balance.
