Camaraderie

Camera speed
Now here is a motion picture film
A thousand feet
Sixteen thousand separate photographs
Let's tidy up this tangle of film
By putting it on a real

Now we'll build a projection machine
To show the pictures on the screen

The film unwinds from the reel
And rewinds onto another reel
After it runs through the projector

To show the picture on the screen
There is a bright light
With a reflector behind it
To send the light rays at the right direction
And a lens to concentrate the light
The film passes a hole or aperture
Which lets the light go through only one picture at a time
There is another lens to focus the pictures on the screen

Surprising as it seems
You never see a motion picture
While it is actually moving

Man eight seven six
We have main engine start
Four three two one
And liftoff liftoff
