I have always wanted to know and now I know. It’s a serious question because quicksand can happen anywhere where sand is saturated by water. 🙂
Wear a tube around your waist at all times and always be around friends.
There really is no way out of quicksand except that the bottom of quicksand usually will not reach past your waist. Most people think that you’ll sink in above your head but that’s not the case. Also, don’t struggle or flail around because it will make the sand and water mixture more liquidly, thus more likely to sink. Another reason is that it will create an air vacuum or something. Anyway, the many times in your life that you do end up fighting with quicksand, just stand up.
