Liquid lock in space?

[Stretchytall]

Can I use a liquid lock to allow my duplicates access to outer space, or will the water get sucked into the vacuum?

use background tiles in your waterlock. everything should be fine

Any liquid or gas with "space exposure" will get deleted at a massive rate.
Having background tiles (either natural or drywall) will prevent that.
And vaccuum doesn't suck in the game, so no worries about that.

On earth the air pressure at sea level is equal to about 10 m of water. On a 1m^2 square that's 10 tons. That's why anything with an atmosphere on one side and vacuum on the other will quickly get to the vacuum.

In oni the air pressure at the top of the map is only what is in that room. Maybe 4-8 kg. It's not enough to push a tile of liquid up into a vacuum tile even if gases could push liquids and even if gas pressure was calculated that way in the game, which they aren't.

If you use water in a liquid lock you have to be careful it doesn't get too hot or cold. Hot regolith can boil a liquid lock and turn it to steam.

For liquid locks in extreme temps use crude oil or petroleum.
