Quicksand
Quicksand is created when water coming up from below ground holds sand and clay in suspension The moving water keeps the particles from sinking to the bottom. If you step in quicksand and get stuck, the most important thing to do is remain calm. You will not get sucked down past your head, you will stop sinking just past your waist. Think about floating in a pool. You float because the water is denser than your body. Quicksand is even denser than water alone so you can float easily in it. It is suggested that you try to lie on your back and float on the quicksand, then slither to safety like a snake. You can also try to crawl out on your hands and knees.
If floating or crawling doesn’t work, try moving your legs as much as possible. Moving your legs allows more water to mix in with the sand, making it easier to pull your legs out. The next time you are watching a movie where someone disappears into quicksand, point out to your friends that it is impossible to get sucked all the way under.
