This strikes us as terrifyingly vulnerable to Murphy’s Law. As one paper notes: “A major shift of weight (all the crew to dinner at one sitting) would require a programmed and controlled counter-movement of ballast.” Let’s hope the pipes don’t malfunction for Friday night potluck—you’d hate to have Mrs. Sanderson’s baked ziti ripped out through a hole in the world.
This is not that hard and “pipes malfunction” isn’t something that’s just going to happen every day like your toilet getting clogged, this would be a major malfunction. Too cutesy and simplistic in trying to make their point.
