You’ve probably played with a remote-control something-or-other, yes? I bet this is cooler: a remote-controlled mini submarine. Better yet, one that we can build ourselves for cheap. A New York Times blog has details: A Mini Sub Made From Cheap Parts Could Change Underwater Exploration.

Don’t you want one? Of course you do. We’d send our mini-sub down to inspect kelp growth at Berry Point, and to film the Quinsam from underneath as it passes by. We’d use it to sneak up on scuba divers and give them something to gawk at. And, and, and!

(Link found here at Boing Boing, which has a few related links, too – like this one: the little submarine that could.)
