This one should be easy enough for everyone to figure it out once you get the idea. simply have one player that will be on a high ledge jumping down into a portal.
player 1 needs to place a portal where they will jump into, and their second portal needs to be somewhere where the ceilings are really close. player 2 then makes their portal on the opposite side of player one's last one, and then player two's last portal can go somewhere on the ground.
Player one should jump through their first portal sending them through their second and into player 2's first portal and out their second making a total of 2 portals you've passed through.
once gravity returns you back to the ground, you'll shoot through the portal's the opposite way, giving you the other 2 and netting you your achievement.
Here's a quick paint model I made to explain how to set the portals.

Easy way to do this is get to the Excursion Tunnel course. Once you come to a chamber with the Tunnels you can change the direction on just have your partner go switch the direction of travel each time you go through the portal.
The beginning of chamber 8 is a great place for this thanks to Snotrocket07 for the tip |

For the easiest way to get this achievement load up Mass and Velocity Test Chamber One and get to the Second Room.
In this room you will have a platform up to your left. Portal both of you up to this platform, now get the person going for the achievement to place their first Portal on the FLOOR directly underneath the platform and their second Portal on the FLOOR across the room. Once both Portals are placed the Achivement Hunter dives off the platform and into their first Portal this will create a perpetual motion between their Portals.
Now the first person (The one still on the platform) replaces the TWO Portals on the FLOOR with their own. The timing is best done as the other player hits their Portal. It is best to do Nearest-Furthest with replacements.
Credit goes to GdC Got Milk for assistance with figuring this method out.

My solution does not require a specific chapter, ceilings, heights, or any gels or funnels. The only requirement is a area on the floor big enough to support two portals side by side.
1. Player 1 puts their portals down on the floor and hops in. At this point Player 1 is bobbing up and down in their own portals.
2. Now Player 2 has to be quick about this but it is easy to do. While Player 1 is in the air Player 2 shoots one of his portals directly under Player 1 and quickly puts his other portal right beside it. Now as player 1 falls he will start to bob up and down in the portals belonging to player 2.
The achievement toast should pop up soon after. I was able to pull this off on my first attempt and even return the favor for the other player in less than a minute using this technique, easy as pie. |

A very easy way to do it is in the mobility gels test chamber 6.
While dropping in and out of the portals at the bottom of the map (in order to use the laser to take out the turrets) just have your partner on the platform place their portals below you. Or if their portals are already below you then place your two portals below you and then you have it. |

| The easiest way to do this is to have 2 portals from one player on the ground (preferably close to each other). You will then want the player who has the portals down to jump into one of the portals from a decent height. This way the player will keep going through the portals back and forth. The other play will shoot his own two portals in the exact same spot where the other two portals were. Make sure you wait until he just exits one so you have more time. Once the player goes through both portals again he will get the achievement. A good spot to do this is Course 3: Hard-Light Surfaces Chamber 5. Another good spot to do this is Course 5: Mobility Gels Chamber 4.

| This is the one I used. Worked out pretty well for me. True credit goes to the creator of the video, not me.

| this is extremely easy, some of the above guides make it look harder than it really is. First, the player going for the achievement needs to place two portals on the ground side by side and the other player needs to place a portal on the ground. The player going for the achievement needs to enter on of their portals--you will oscillate between the portals quickly as they and you are both on the ground to begin with. After you rise above and then go back through each portal once, the second player needs to shoot his/her second portal under the first players feet after they emerge from one of the portals, causing that player to begin oscillating between their portals. In all this achievement takes about 20 seconds--it is very easy to get. |

| I got this on course 5 chamber 6, but you can get this in multiple places. When you are flying out of your partners portals and facing the "fake" defective turrets, make sure you fly into both of your partners portals and after that, while in the air, switch them with your own and just fly through both of them and that should unlock the achievement. |
