I am interested in the property of a cornmeal/water mixture by which increased pressure causes the mixture to solidify. I think this was a demonstration of some property from high school physics. What is this propery called?
I’m also interested in other substances that have this property. Is there some substance that could be put into a flexible container like a ziplock bag, that would offer more resistance to bending at high pressures, but not as much at low pressures?
Sorry I’m so vague. I searched Google and SDMB for a while, but all I got were recipes for mush and gruel.
