It's beginning to look a lot like science!
Everywhere you go!
The chambers are alight, glistening so bright!
With weighted-cubes and turret eyes aglow!

It's beginning to look a lot like science!
Cores on every rail!
But the prettiest sight to see is the testing that will be!
It'll be quite the tale!

A pair of long-fall boots and a portal-gun that can shoot...
Portals straight through the air!
Guns that can talk and robots that can walk!
Oh, they give the subjects a good scare!
And GLaDOS cannot wait for the testing to start again!
[Defective Turret]
And us turrets cannot wait to start shooting our guns again!

Ohhh, it's beginning to look a lot like science!
Throughout, it can be felt!
There's a tree in all the motels, and some in the goo as well...
[Defective Turret]
The sturdy kind that simply doesn't melt!

It's beginning to look a lot like science!
Soon the gas will spread!
And the thing that will make them die, just before we say goodbye
Is the gas within...
Their heads!
[White Turret]
Goodbye
