*Head for the elevator shaft and jump down.

*Shoot a portal on the floor and put the other portal on the white surface behind the fence. Go through the portal and duck.

*Walk towards the two moving pistons and go stand on the one that goes higher up. Wait for the piston to be extended and then fire a portal on the surface above your last portal.

*Go back to the portal you've placed before and jump through it.
