Saw these downstairs of my block. They were in the middle of some construction work. One day suddenly I saw these there.
They look exactly like the reef balls we see underwater don't they? I wonder what is it for? Can't be that they really are making reef balls.. cos they are in the middle of some construction work. But if they are not reef balls, if they are made for construction purpose, what is it for??
Perhaps it really is for construction purpose and the person who invented reef balls got the idea from here.
