Just put liquid in the main room (on your left side of the large room)

TO MOVE LIQUID?
no problem! should be a entrance to the large room on floor 2 is the main entrance (on floor 1 is sub entrance)

WHAT THE ROOM CALLEDWITH THE ONE WITH 2 ENTRANCES?
good question! its called the rubish area!

WHAT DOES THAT TINY ENTRANCE LEAD TO AT THE END?
behold algodoos sientists invention... drum roll plz! BEHOLD THE BOILER that part at the end makes the steam! (erasing your liquid)

EDITS!: Gears to make it easier, trap doors to control liquid flow and finally a filter so you can stop any non liquidfied rubbish in!
