GIRL: That's Logan, Erica and me.
We're filling up the pool.
ERICA: Now we're going to make some islands
out of bricks and rocks and a few plastic containers.
GIRL: We made two little islands.
ERICA: We're going to put some boats
on each of these islands
and we're going to see what happens.
GIRL: I think some things might float
when we fill up the pool.
Okay, turn the water on.
(water splashing)
The water level is going up.
Some things are starting to float.
This is the higher island.
The taller island, it was harder to get the things off of it.
We had to wait for such a long time.
Then once we saw everything come off,
it was really fun.
ERICA: All of the little plastic toys float around.
Now we are going to let the water drain out
and see what happens.
GIRL: Erica pulled out the plug.
ERICA: The water's draining out.
GIRL: The rock island is above the water again.
(laughing and shouting)
ERICA: When we pushed down the sides,
the water and our toys came out.
See what happens when the level of water changes.
