NEW How to use doors to breathe Underwater LATEST UPDATE HD

I never knew about this until recently while making an underwater base. apparently its old but claiming to be a glitch. I havent seen anyone show this on the legacy version and on the latest version on ps4 so thats why im uploading it. Someone might have already but i didnt find it. This is how i managed to make an easy cheap access to the bottom of my farm. Im sure people can think of much better uses for this.
