Nope. Quicksand—that is, sand that behaves as a liquid because it is saturated with water—can be a mucky nuisance, but it's basically impossible to die in the way that is depicted in movies. That's because quicksand is denser than the human body.

Picture this, you’re having a nice, relaxing walk on a private beach without a care in the world. All of a sudden, your foot drops into a  deep and murky puddle. You struggle to pull your leg out, but it just won’t budge.

Before you know it, you’re sinking rapidly, and half of your body is submerged in cold, wet quicksand. The more you struggle, the more you sink. Talk about a terrible way to end a vacation.
