This is an old-ass video of somebody's (the French's?) Navy detonating an underwater mine. The picture quality is pretty poor but the explosion is amazing and I'm not afraid to admit I got aroused. Twice. Plus I love how at the very end they realize their boat's gonna be capsized by the resulting wave and start going apeshit. Talk about poor planning -- that's something I would do! But it's cool because I'm a blogger and not a Navy.
Thanks to Trogdolorian, who plans on traveling back in time to seize and burninate a castle.
