Facts about Quicksand |
|
|
- Quicksand is not a special type of sand. It’s just very fine sand that has become super-saturated with water. That means completely soaked.
- Quicksand usually forms near rivers, swamps and beaches. It can also form wherever there is a water source, like an underground spring, that flows under sand.
- You can walk across normal sand because each grain touches another. They press together and friction holds them in place. When the sand gets saturated with water, each grain is surrounded by water molecules and doesn’t touch the other grains near it.
- If you find yourself in quicksand and are not too deep, lie down on your stomach or back. By being flat, you create more surface and can float on the top.
- With quicksand, if you struggle you will sink faster.
- Fortunately, quicksand is not really that common and it’s usually not very deep. The movies make it look much more dangerous than it really is.
