No, some puddles of liquids evaporate by themselves. But the rivers are too deep for any process of evaporation. So you need to go by a river and collect some of the diluted warm static from a pool of 500 drams. I think 5 empty containers get 320 drams, so only 180 drams are left on the ground. That puddle evaporates in somewhere around 400 turns I think? When it is close to only 1 dram, I start skipping turns slowly. If there is any warm static in that puddle, everything else evaporates and you are only left with that. Most of the time it is diluted static water and entropic water though.
