Before you can make one, you have to have Craftsmanship level 2, so craft other things until you level up. For this, you need your Flask, a Palm Frond, one Lashing, one Cloth, and three Rocks. It is found in the Construction portion of the crafting table. How to use a Water Still in Stranded Deep When you have crafted and placed the Water Still, you can have it create water over time by putting up to four Palm Fronds in the bottom part of it. It will automatically build up water when it rains if you don't have any.

When you have it in your hand, go to the Water Still, and you can fill it up if it is empty and there is water in the structure. It will take one-quarter of the max water in the Still.
