Quicksand

How quicksand looks in-world

Not to be confused with Quicksand from Elithian mod, which is a different thing.

Quicksand is unobtainable liquid that only exists in-world: when mined, it turns into Loose Silt items. Loose Silt can't be turned back into the liquid form.

It exists as small puddles/lakes on some desert-like planets, but is relatively rare.

Players who swim in Quicksand are affected by "Quicksand" debuff, which reduces the mobility for a short period of time (similar to Tar).
