The Possibilities Are Bottomless

New Dutch research finds that sand can swallow a man alive even when it is dry, provided it has been air-puffed. Watch for this to pop up in gadget movies. How cool would it be, say, to have a moat of dry sand?! Or a maze where contestants must stay on solid trails or find themselves swallowed up by the desert?

On a more practical tone, the researchers note that "The U.S. Army is very interested in this, because these days, the U.S. Army tends to go to desert states." [NYTimes]
