Everyone who's grown up with Legos has mused about the limits. Could I build a car? A house? A boat? Now you can tell your inner child: Yes! Just don't let him watch the end.

Japanese boy band Arashi constructed a boat capable of keeping the whole group of four afloat, assisted only by the natural buoyancy of the boys' whimsy. It worked! For a while! Then, as you can see for yourself, things fell apart disastrously. The only salve I can offer for your bruised, waterlogged dreams is this: Japanprobe thinks the Legos are knockoffs.

OK good, now that we've got that settled, next we shall conquer the sky! And by we, I mean Japanese boy band Arashi. [Japanprobe]
