[titre] With Fernand Seguin
La science en pantoufles: Board 4 Fernand Seguin and Marc Favreau seated, near a counter, and Mr. Seguin conducting a demonstration with water and a chemical product.
Fernand Seguin: There is water in this container right up to its edge.

Marc Favreau: Yes.
La science en pantoufles: Board 5 FS: So, if I add this chemical substance...

Marc Favreau: What is it?
La science en pantoufles: Board 6 FS: Ah! This is urea. It is the main constituent of urine, but this is not important. So if I add the substance, will the liquid overflow?
La science en pantoufles: Board 7 Marc Favreau: Ah! Well yes, of course!

FS: Uh huh...
La science en pantoufles: Board 8 Close up of hand Fernand Seguin.
Marc Favreau: Ha! That's funny, it looks as if there is no change in the volume!
La science en pantoufles: Board 9 FS: And if I were to add some more?
La science en pantoufles: Board 10 Fernand Seguin and Marc Favreau seated, near a counter, and Mr. Seguin conducting a demonstration with water and a chemical product.
Marc Favreau: Well, now I am pretty sure the liquid is going to overflow.

FS: Well, watch closely!
La science en pantoufles: Board 11 Marc Favreau: It is truly a magic powder!

FS: I think I will add some for a third time.
La science en pantoufles: Board 12 FS: That's a lot, right?

MF: It sure is.
La science en pantoufles: Board 13 MF: What a fine trick this is!
La science en pantoufles: Board 14 FS: Why didn't the liquid overflow?

MF: I have no idea.
La science en pantoufles: Board 15 FS: Well, it is because the atoms of this substance positioned themselves in the spaces between the atoms in the liquid.

MF: Oh!
La science en pantoufles: Board 16 FS: Here I am going to show you another example. Remove that, and now plug it!

MF: Now?
La science en pantoufles: Board 17 FS: Now.

FS: I imagine you would like to see how small they are, right?
La science en pantoufles: Board 18 MF: Yes... Euh You say they are smaller, but they can be measured? Can we see them? Smaller than that? About how small?
La science en pantoufles: Board 19 Close up of hand Fernad Seguin and water on the table.
FS: Wait Hum! Here: in a thimble the size of this one filled with water, do you know how many atoms it contains?

MF: No.
La science en pantoufles: Board 20 Fernand Seguin and Marc Favreau seated, near a counter, and Mr. Seguin conducting a demonstration with water.
FS: Well, there are 30 billion billion.

MF: 30 billion billion!
La science en pantoufles: Board 21 FS: Now, can you imagine how big that number really is?
La science en pantoufles: Board 22 FS: Suppose that your ancestors, at the time of birth of Jesus Christ, had 30 billion billion dollars, OK?
La science en pantoufles: Board 23 FS: If, since the birth of Jesus Christ your ancestors had spent 400 million dollars per second... Well, there would still be enough money to spend until the year 2000.
La science en pantoufles: Board 24 MF: Wow! That's incredible!

FS: And that merely represents the number of atoms in a thimble full of water.
