I Coulda Beena Millionaire

The army is evidently testing a Liquid Body Armor that is supple and flexible during normal wear, but hardens on sudden impact.

Does anyone remember the "Stretch Armstrong" toy from Kenner in the 70s? It had the similar property of being able to stretch up to 4 times its normal size. If you squeezed it slowly it would deform like silly putty, but I found (by painful experiment) that if you punched it, it was solid as a rock. I remember thinking at the time that you might be able to use that fact to make a kind of armor but, being a kid, I didn't pursue the idea.

Well, it looks like someone else did. Neato!

(I got this from somewhere in the churning cauldron of Free Republic.)
