What to do?
What you need? The experiment
20%water 80%corflour
We realise a non newtonian fluid
Cold temperature Ambient temperature
When you hit the oobleck it is solid
When you move slowly it is fluid
Cornflour is a polymer composedof starch molecules.
When the oobleck is solid when the oobleck is liquid Molecules tangle molecules slide against one another
Quicksand is a non newtonian fluid
It is a dilatant fluid like the oobleck
Although sand grains are much larger than molecules of starch, starch molecules are quite large and quicksand may react very much like the oobleck.
If you struggle you solidify sand all around you and you are trapped, so you have to move slowly and you need someone to help you to get away.
In every way, as you body is twice less dense than sand you can not drawn yourself , you will float in quicksand.
