Over on the STORROR YouTube channel, a guy named Callum Powell can be seen leaping into a huge pile of quicksand, and unsurprisingly, he starts sinking pretty quickly.
While the other guys in the clip start laughing, Callum sinks to his knees pretty quickly before holding his hands out for help.
Although the video doesn't actually show how Callum managed to get out, people were all saying the same thing after watching.
Most of us have seen quicksand in TV shows or movies.
Brittanica explains that quicksand can be tricky to get out of because it behaves like a liquid due to how saturated it is with water.
If you do find yourself in quicksand, it's best to lean your body back to distribute the weight.
"Moving won’t cause you to sink. In fact, slow back-and-forth movements can actually let water into the cavity around a trapped limb, loosening the quicksand’s hold," the site explains.
"Getting out will take a while, though. Physicists have calculated that the force required to extract your foot from quicksand at a rate of one centimeter per second is roughly equal to the force needed to lift a medium-sized car.
"One genuine danger is that a person who is immobilized in quicksand could be engulfed and drowned by an incoming tide—quicksands often occur in tidal areas—but even these types of accidents are very rare."
In Callum's case, although he eventually did make it out, people were quick to comment.
Many explained that as kids, quicksand was often seen as a terrifying danger.
One wrote: "Why did I think quicksand was the greatest threat to my life as a child."
While another said: "We were warned about this throughout our entire childhoods in cartoons and comic books yet he literally just jumped in."
And a third added: "Can't even begin to explain how much I thought about quicksand as a child."
Meanwhile, a fourth commented: "Same - didn't know what was going to get me first... quicksand or a glacier."
"As a kid I believed I would encounter this situation regularly as an adult," said a fifth.
Although not particularly common these days, quicksand was often used in cartoons and movies, so perhaps that's why it's associated so heavily with childhood.
"TV really made me think this was important stuff to know," one person added.
