I know, sounds odd but would a normal brick release anything in to the water?
Found them on a building site im currently working on, ther are square and hollow, i got 6 of them and put them together it makes an interesting tunnel... Im currently soaking them and nothing so far, just wondering if anyone knows anything about it?
Thanks
