ONI | How to build a 3 Liquid Waterlock

Wait for something really hot to pass through that lock to ragequit

The second you removed the 2nd tile and my brain saw 2blocks of liquid on top of each other without it pouring out my brain had an error404

I find that it is easier if you simply line up 3 tall airflow tiles with the bottle emptier at the top, then leave 3 tiles wide for the gap, and repeat with the other side, 3 tiles of airflow high. Select your 3 liquids, and deliver to the bottle emptier in their stack order, and once done, you should switch to the next. Upon completion, simply put a mop command in the bottom right (or left) corner next to the airflow tile to mop up 2 tiles wide, and this leaves you with a single tile of liquid stacked 3 tall.

Using Naptha isn't a bad option (despite needing to melt plastic) as it's initial single tile blob count is 30kg, which drastically reduces the chance the liquid lock gets damaged, though i'm not sure what would be best to put on top (or bottom) of that.

And why would anyone need that?

ethanol wouldnt work for something really hot. itd evaporate

that's handy

Good
