a housing comprising an open top, an open bottom, and a sidewall extending between the top of the housing and the bottom of the housing, wherein the sidewall of the housing comprises a plurality of ridges on an exterior surface of the sidewall of the housing that are parallel to the at least one ridge of the first sidewall of the cap and are configured to engage, in sequence, with the at least one ridge of the first sidewall of the cap; and
a chamber attached to the cap and configured to be inserted into the housing, the chamber comprising an open top and a perforated bottom, wherein the top of the chamber comprises an opening configured to allow the center arm of the cap to extend into the chamber and engage a stopper located within the chamber that seals the top of the chamber;
