How to get The Aquanaut Achievement/Trophy

To get The Aquanaut achievement/trophy you need to collect two yellow rubber ducks in Chapter 6 (Tombaugh Facility). You will be able to do this about halfway through the chapter when you enter a flooded theater area and then go through a central corridor. On the right side of the flooded hallway is a tube which if you move the ASE through it will push the first rubber duck out.

The second rubber duck can be collected after you have solved the small electric puzzle in the water (the code is 8662). Solving the puzzle will push the empty canister back so you can use it to jump out. If you now turn left and head back through the previous room and take a door on the left side into a flooded hallway that leads to a flooded room you will be able to collect the second duck.
