If you aren't already familiar, there is a bug with beds that allows you to break them while you're sleeping in it, which gives you a weird collision box. After playing around with it a little, I found that jumping into water while this glitch is active will let you walk through it as if it were air. This used in conjunction with the classic ladder trick could making underwater building and mining much less tedious.

Here's a video demo

Do you lose bubbles (as if youre in water holding your breath) or does it not recognize you being in water at all?
