so, i need a little help with this one. in the women's shower at the astronomers lodge of parkes observatory, there is an odd feature. see in the photo below, the little shelf down low? well, it's not flat at all. in fact, its at such a steep angle that you cannot rest anything on it.
the other little shelf was full, so i went to place my soap on that dish, but noticed it's steep angle and thought - huh? and then wondered why there would be a shelf so low anyway?
so my question is - what the heck is that thing for?
