It's really easy to do that in Fort Frolic. Just possess the Big Daddy in the main room and go to Poseidon's Hall to see one come down the stairs
But there's other enemies there
But the easiest way to do it is at the second Bathysphere in Fort Frolic. Possess one Big Daddy and lead him all the way to the stairs in front of the bathysphere. Shoot him once and stand at the bottom of the stairs. Wait till he charges then he should slide into the bathysphere. Hide behind the lever and if he's in far enough, he'll just stand there hitting the ground. Peek out a bit and hit him with the crowbar (as long as you're next to the lever he won't hit you unless you get into range of him) and it goes by faster when you have the 3 crowbar upgrades
