GIRL: We're going to make a house for our toys.
I'm trying to use tubes to hold up a piece of cardboard.
It's not staying up.
So I'm putting thick pieces of cardboard together.
Tape really helps.
This is how we'll make rooms.
We're going to bend the pieces of cardboard.
If you put a piece of cardboard down
and let it go, it falls down.
But if you bend a piece of cardboard, it stays up.
Vuthy make a room for his bear.
And there's Eric's room.
The rooms are holding up the second floor.
These are the stairs.
Want me to install them?
GIRL: Vuthy said he would install the stairs, and he did.
The room I made is going to be the second floor
and my room is holding up the roof.
VUTHY: I wish it was raining to see if it can stand.
The roof is working,
and it's kind of getting wet, but it's okay.
Ohh!
VUTHY: He's not even wet.
He is-- look.
(laughs)
Her hair looks gnarly.
Gnarly, dude-- gnarly.
GIRL: Find some old boxes and try building your own house.
