La répartition des forces

Today, we're discovering all kinds of mousse. Did you know that a cake is a solid foam? Daniel reveals the secret of aerosol cans, and he and Yannick carry out a super-foaming chemistry experiment!

How do clouds, rain and fog form? Thanks to condensation! In his laboratory, Yannick uses condensation to first produce a small rainfall. Then he creates a giant effect!

Daniel is interested in baby wipes and diapers. Why is that? They're absorbent materials. We discover that a diaper contains a super-absorbent material that allows Yannick to perform some super experiments.

Daniel is interested in magnets. How are they made? What are they made of? Which magnets are the strongest? To answer Daniel's questions, Yannick performs some surprising experiments.

What's the link between a drinking straw and the suction cup on a dart? Both are powered by air pressure. Together with Yannick, Daniel discovers that this pressure is actually very strong.

Today, we discover some surprising effects of cold. Daniel explains why ice cubes sometimes stick to our fingers.

Today, we take a look at the science of soap bubbles. Daniel explains why soap bubbles pop on their own. Yannick shows us how to get stronger soap bubbles, and even giant ones!

What do a kernel of corn, a paper bag and a party balloon have in common? They all make a small explosion noise when they burst due to the movement of air.

Daniel explains that ketchup is a mixture that is both solid and liquid. It's a colloidal substance. In his lab, Yannick makes an amazing colloidal substance.

Yannick uses the science of light to make objects appear and disappear in water. We also discover how it's possible to bend a pencil without breaking it. Daniel manages to bend a spoon using the magic of water.

This episode focuses on gases and their weight. Daniel explains to us why a helium balloon rises into the air. In his lab, Yannick shows Daniel gases heavier than air. Daniel performs an astonishing magic trick with a helium balloon.

When you spin an object quickly, amazing things sometimes happen. We can even defy gravity! Yannick shows Daniel some surprising experiences. Daniel performs a stunning magic trick with cards.

After watching this show, fireworks will no longer hold any secrets for you! Daniel explains to us why a Bengal fire produces sparks.

Today, Daniel has fun mixing liquids that don't mix. Yannick shows us that not all liquids have the same weight. Using seven liquids of different densities, Yannick performs a surprising experiment.
