Looks soothing. Too bad about that oil tanker running aground, but on the bright side, a Greenpeace volunteer might towel you off when you get out (seriously though... what's with the dark water? No one else is saying anything... is it a well known bath product? Well known disastrous state of America's public works? Maybe your tattoos were all done with Sharpie and now they're coming off?).
Righto. I assumed it was something like that, but I've never used one myself. Dark water actually looks cosy, like bathing in night. Do they make bath bombs that glitter, so you come out of the bath sparkling like a Twilight vampire? It would get glitter everywhere, but it would look impressive. Something to use just before moving, perhaps.
