I would have to agree with Serge 09:46 Nov 4, 2011
The idiom is quite clear and it does not really matter in what context (context was given in the first discussion post, by the way), as it is a clear image: trying to get the water away while the tap is wide open, thus performing a useless activity with a clear goal that is achievable, but not in these circumstances. On another website I saw the idiom (not widely used, but I think it could be quite fun) 'emptying/trying to empty the ocean with a thimble'. Thus evoking the idea that the water will keep flowing into the ocean through the rivers and you are trying to empty the ocean with your thimble. |
