Ocarina of Time Master Quest - Hydro Lift II
- Enter the Spirit temple.
- Up the stairs to the east is a jet of water. Go to where either side of the jet meets the wall and run/roll into the jet.
- As you begin to get pushed out press B (you must already have your sword out) to do an attack.
If done correctly you will not be forced out of the jet and will end up on top of it (as child Link, as adult Link you get crushed when you touch the ceiling). From here you can jump into the void, back to where you came from or into the area on the other side normally only accessible by adult Link.
Be careful not to use any small keys you may have while in this area, if you do so and save your game you will be unable to complete the temple.
