Incidentally, you also shouldn't listen to pop culture when it comes to surviving a grenade attack. Gonna pick it up and throw it back at the enemy? Good luck, Johnny No-Fingers: The fuse gives you three to five seconds, at least two of which were spent while the grenade was traveling from the hands of the enemy to you. Running won't do much, as the blast radius is 30 to 35 feet, and you're not that fast. Don't try covering it with a helmet or sticking it inside a container like, say, a fridge. The grenade is supposed to explode in a way that spreads shrapnel, and you've just given it more ammo.
It's Nearly Impossible To Drown In Quicksand
In spite of what Hollywood shows you, quicksand is not nature's Sarlacc. In fact, unless you dive in face first, it's unlikely to kill you at all. Like lava, quicksand is far denser than the human body, so while it might pull you in waist-deep, there's no way for it to suck you in all the way. Researchers have found it strangely difficult to recruit volunteers for their "Hey, try to drown in this quicksand" experiments, but the classic movie-style sinking scenario has been simulated by throwing beads with the same density as the human body in facsimile quicksand. They never dipped more than halfway, and actually resurfaced on their own after a while.
So, if you ever find yourself stuck in quicksand for reasons we generously assume are not related to raiding ancient temples, here's what to do: Resist the urge to try to yank yourself free. If you try pulling yourself up, you will fail, and the sand's strong downward pull means any potential rescuers attempting to tug you out are more likely to tear you in half than save your life.
Which makes this scene even stupider than before.
If you don't want to just hang out and play some Kim Kardashian: Hollywood on your iPhone until the sand particles settle naturally, researchers advise that you ... wiggle your legs around. No, seriously. Wiggling about creates a space where water can flow and make the quicksand around you looser. Do this slowly and progressively, and eventually the earth will vomit you forth like the indigestible idiot that you are.
