  Unless you panic and thrash about. The force required to pull your leg out is more than the force of buoyancy keeping you up. So if you are up to your hips, and you just try to step out, you will keep sinking. Once your chest is under, it will be hard to breathe and the panic gets worse.

    Could be. I have never encountered quicksand but I have heard that you don’t really sink past your waist.

      Most quicksand probably isn’t that deep, so you’ll end up standing on a more solid layer

        Exactly. I doubt there is a 2m deep pit of quicksand I need to be worried about

      i believe it follows similar laws as water and buoyancy. you slow/stop sinking once the displaced water/force is greater than whats above the sand. Similar to deep eater, panicking only allows you to sink more.

    Nope. Sand+water is less buoyant than you. You float. Death comes from dehydration or exhaustion. Not from drowning.

      I’m not sure you read my comment.

        So how do you get out if you’re alone?

        If you remain perfectly still, you’ll stop sinking at your waist

        I’m not sure you understand buoyancy. Floating objects float, they don’t sink no matter how much thrashing about. And while quicksand is denser than water, it’s still not dense enough to float a human at their waist, it’s actually around their chest.

        Nobody dies from drowning in quicksand. Ever. It’s always dehydration/fatigue.
