Okay, so I try not to lift stories straight off of Slashdot, but this is amazingly cool.

The article, from New Scientist, talks about the work being done on supercavitation, essentialy, creating amazingly fast underwater projectiles and, conceivably, ships by creating a standing cavity in the water that the object flies through, instead of relatively dense water.

As interesting as this article is simply on its own merits, I like it because it shows another example how an area we think is relatively hammered out, underwater travel, can make a huge leap. It's things like this that give me hope for interstellar travel, and these guys are just the ones to take us there. Well, it's more likely than this menagerie.

It makes me wonder if "What to do if you're floating in a vacuum" is covered in The Worst-Case Scenario Survival Handbook.
