The concept is like ketchup. The more you shear it (ie, stir it), the less viscous it gets. (To a point). So, if you stay still, it will remain viscous and support your weight. But if you thrash about, it will become less viscous, and you will sink. Like how if you upend a ketchup bottle, the ketchup will stay put, but if you shake it, the ketchup flows out.
In the case of ketchup, this is called being thixatropic.
