There are always moments where you are low on water and you need to drink something. Maybe instead of dying from dehydration, we can purify dirty water? I know this is a very common item in survival games, so it probably will not be added, but I feel like this can be a good addition. It could use the acorn top to funnel water through, and silk rope to separate the dirtiness from the water. I just thought about it, I don't think it is going to ever be added since Grounded is a very unique game, and I think it wants to stay that way.

Don't we have the dew collector ?

that's why i have multiple small camp site all over the yard with dew collectors and acorn water barrels. that way there's always some where close.  i also have 2 of the upgraded canteens that hold four servings with me. might make a couple more because the heat of the sandbox makes your thirst level drop a bit faster. there is also the dew drops that can be found on some grass stalks. and with the addition of the milk molar upgrading, you can slow the burn rate of your thirst so you don't need to drink as often. 

So this could be possible with the objects in the game currently, if in the future when the charcoal chunks become more plentiful we could use burned out charcoal as a carbon paste together with a canteen+ to create a canteen that we can use to filter dirty water.
