Okay, turn the water on.
GIRL: Keenan is spraying some water in the pool.
Some things are floating, other things are not.
We're going to drop them in the pool.
And see if they float or sink.
I think it will sink.
KEENAN: I don't.
GIRL: I think it will float.
KEENAN: And it is floating.
GIRL: Emma found a little tube.
EMMA: It sinks.
GIRL: She is blocking up the holes of the tube
with the seed pods.
I plugged up the holes.
So it wouldn't breathe.
EMMA: It floats.
If I put these out,
the water can come in and it will just sink.
This is a walnut with skin on it,
and this is a walnut without skin on it.
GIRL: The one with the skin is sinking,
and the one without the skin is floating.
The one with skin has no lines on it,
and it puts heavy weight in the water, and that's how it sank.
And the one without skin, it has lines on it,
and it doesn't have heavy weight,
so that's how it floats.
GIRL: Try putting things in the water
to see what floats and what sinks.
