The buttons are getting a bit high and mighty for my liking.
What do I do?
Throwing the cube is out of the question, but how else can you get it up there?
Hmm...
Try looking a little closer at the ceiling.
Help me out.
Shoot a portal at the 'dot panels', and you'll find that they're directly above the buttons.
That'll make dropping a cube onto them fairly easy.
But there's two buttons!
Aren't you forgetting something?
There's two cubes, too!
Hmm...
The other cube is in the starting room, but taking it off the button will close the door.
So what do I do?
Can you make sure that the door being closed doesn't matter?
Put a portal in the 'main' room, and shoot another one into the starting room. Take the cube through the latter portal into the 'main' room, where you'll be free to put it on the other pedestal's button.
With the door open, you can shoot a portal inside (through the mesh if necessary) and reach the exit.
