Norman Wagner at the University of Delaware and Eric Wetzel at the US Army Research Lab in Aberdeen, MD, have invented a liquid armor that may soon lead to light, flexible full-body armor.

I wonder if the it returns to the semi-liquid state after hardening up.

Larry Niven called this “impact armor” in his “Known Space” stories…
“…Louis ran along the fence toward the walkway. The soldiers were close… The roar was disconcerting, even terrifying. A slug slammmed into Louis’s ankle; the suit went rigid, and he rolled like a tumbled statue, picked himself up, and ran again. As two soldiers threw themselves at him, he swung over the fence and dropped…
Louis landed flat on his face, in an impact suit gone rigid as steel. The form-fitting coffin supported him, but he was still stunned…”

You can do a variation on this at home with cornstarch and water. Fill a medium sized bowl with cornstarch and water to a gooey consistency. You can pour it, and dip your hand in slowly. If you punch it, however, all the molecules line up with the agitation and it will be rock solid.

And for the real geeks out there who want a word to drop into casual conversation, materials with the property are called ‘inverse thixotropic’ or ‘rheopexic’.
