The Sound Princes sdevice from Otohime is an electronic “flush” that not only helps you out in embarassing situations, it also helps save the environment by minimizing the use of water. After all, Japanese ladies are pretty modest with the kinds of noise they make while relieving themselves in the loo, which led to them repeatedly flushing the toilet so that whatever sounds being created would be masked by the torrent of water. The Sound Princess recreates the flushing sound without wasting a drop of water, where waving one’s hand right over the front sensor will automatically activate it for approximately 25 seconds. Now that’s a pretty long flush if you ask me, so thankfully they can be stopped by pushing a button on the Sound Princess. I wonder if the sound also includes the tank refilling itself, as not having that would give the game away.
