If you open the captains quarters door and ballast door, run from the captains quarters pump and press space at the top of the small staircase, you yeet yourself perfectly into the ballast water. I have no clue if this was intentional but it's fun. If you do it off the reactor rooms small staircase you slide up the large stairs up to decon/fab. Might use this concept to make a sub that supports this as a way to get around faster.
