A container having a disc, plate or the like located therein part way between the top and bottom of the container. In this disc there are provided a plurality of conical or similar structures, some extending above and some extending below the disc. These structures act as funnels. Structures extending generally below the device have their larger ends uppermost, and others of the structures that extend above the device have their smaller ends uppermost. Water or other fluid that is to act on the material in the container below the disc enters the wider ends of the dependent funnels or hollow structures to mix with the material under the disc, and the solution rises to exit through the inverted funnels or structures having their smaller ends uppermost.
