Without surface tension it would stick to whatever thing attracts it more. And a normal piece of cloth attracts water way more than a normal non-carpet floor.

But it also wouldn't flow freely as the GP expects either. Some oils have almost no surface tension, and they are famously a nightmare to clean up.

As a positive, the water would evaporate faster.

the cloth attracts it because of the capillary action pulling water into the gaps therein, and capillary action relies on surface tension! i think without outside forces like suction, the liquid in this scenario would never flow against gravity.

i think hahah

Surface tension doesn't tell you anything about the cloth-water interface.

late reply but i ONLY JUST CONSIDERED, the cloth would most likely have some static charge which WOULD result in a literal “attraction force” towards the water!

physics is so stupid, i love it so much

i mean it’s literally why liquids wick into cloth
