Sandustry Wet Sand: How It Forms and Why It Matters
Wet sand is one of the clearest examples of how Sandustry makes materials interact instead of staying abstract. When sand absorbs water, it changes state, and that change sits at the center of the early production loop.

How Wet Sand Fits the Loop
Wet sand is where the game stops treating water as a helper and starts treating it as an input that changes the material you are moving.
Sand absorbs water
The transition from sand to wet sand is a moisture interaction, so keeping a predictable water supply is the first requirement for reliable wet sand.
Control the moisture
Early setups fall apart when water leaks or routes become inconsistent, which is why wet sand processing is tightly coupled to early game reliability.
Shakers turn it into Gold
Wet Sand is the Shaker's input: each pixel always leaves Residue and has a 1-in-4 chance of dropping Gold through the machine.
The first systems test
Wet sand matters because it forces you to treat water as infrastructure. If your water routing is messy, your wet sand supply becomes unreliable, and everything built on top of it turns fragile.
