![]() Aluminum, for example, has a density of about 2.7 grams per milliliter. ![]() You would descend about up to your waist, but you'd go no further.Įven objects with a higher density than quicksand will float on it-until they move. At that level of density, sinking in quicksand is impossible. ![]() But human density is only about 1 gram per milliliter. Quicksand has a density of about 2 grams per milliliter. The reason is that humans just aren't dense enough. This causes a trapped body to sink when it starts to move.īut a person moving around in quicksand will never go all the way under.
