:29:00
Here's the thing
I thought we could use.
:29:08
It's beautiful.
:29:11
She needs a little work.
:29:13
I think this used to be called
a Tilt-A-Whirl.
:29:16
Oh, it's perfect!
:29:19
We can all fit in here too.
:29:23
Yeah, well...
:29:25
...how are we gonna
get this thing home?
:29:29
It's got wheels. We'll roll it.
:29:36
Turn it around. Turn it around.
:29:45
Come on.
:29:46
That's my foot, you idiot.
:29:48
Sorry.
:29:56
That's enough. That's enough.
:29:58
That's all right.
:30:00
Oh, that's enough. That's enough.
No more. It's fine here.
:30:04
- What time is it?
- I don't know.
:30:06
- I got a test tomorrow.
- It's so late.
:30:08
- So do I.
- Mrs. Doyle hates me.
:30:10
OK.
:30:11
So who would like to tell us something
about carbon dioxide?
:30:18
Ben.
:30:20
Carbon dioxide.
:30:22
That's what you breathe on Mars.
:30:27
They have dust storms
for months there, you know.
:30:29
- And...
- Stupid.
:30:31
And the temperature's 50 below.
:30:35
And that's what you'd breathe
on Mars.
:30:37
- What a geek.
- What is he talking about?
:30:39
And...
:30:49
- Trisha.
- What?
:30:51
Carbon dioxide is formed
:30:52
during respiration, combustion
and decomposition.
