About quicksand

Quicksand is a mixture of light soil,clay or sand and water.Water lets the grains of the soil or sand absorb it and therefore separates and lifts them.That causes the grains to tumble over one another,and makes it impossible to support weighty objects.The quicksand will remain stable if it is left alone. However,when you fall into it,all the sand sinks to the bottom and the water flows to the top.So it is not possible to drown in it as in the end the furthest you can go is on the layer of sand at the bottom.You may get stuck in it but you can never drown in it.
