HELP! Portal - Test Chamber 19 - SPOILERS!

HELP!

First of all I finished this game once, but now I'm stuck six months later after trying it again.

I'm in Test Chamber 19 where there are all the turrets in the big room. I disabled all of them.

There are two 45 degree overhangs on the walls. I have dropped from the upper room into one portal and ejected from the upper overhang, and fell to the ground into another portal ejecting me from the upper overhang again and I can never seem to reach the upper catwalk. I just can't get high enough.

What is the secret again? It's driving me NUTS!

Thanks.

 

The VGcats video made you want to go back didn't it?

 

The secret is to do the following. I'm going to use red and blue, but you can reverse them, as long as you do it consistently :

Get above the lower 45-degree outcropping.

Put a blue portal on the lower 45-degree outcropping, then jump from your heightened position.

Shoot a red portal at the ground before you land to shoot out of the 45-degree outcropping.

As you fly through the air, shoot a red portal at the UPPER 45-degree outcropping.

As you FALL through the air, shoot a blue portal at the ground before you land to go flying out of the upper 45-degree outcropping at terminal velocity.

This SHOULD catapult you into a new room with two turrets.

Get rid of both turrets, then examine the ceiling for a hole that is too high for you to jump through.

Shoot a blue portal underneath the hole,

Run back to the entrance of the room you shot into and jump off the edge, shooting a red portal at the ground before you land to go flying up and out of the blue portal and into the next area.

Voila, c'est magnifique!

 

Ahhhh! Thanks. I was thinking I had to bounce up to the platforms at the top of the middle of the room... d'oh! Just finished it again. Great fun game. Can't wait for Portal 2.
