1. A multi-layer control device comprising:
a first layer having at least one first opening formed therein;
a second layer having at least one second opening formed therein, the at least one second opening being positioned distal to the first opening, said first and second layers being joined together such that there is a space separating the first and second layers and defining at least one first channel between the first and second layers, the first channel selectively permitting gas flow from the first opening to the second opening of the second layer;
a third layer covering the second layer, said second and third layers being joined together by a second adhesive layer, the second adhesive layer defining an adhesive free path in communication with the second opening of the second layer and extending to a perimeter of the third layer such that at least one second channel is defined between the second layer and the third layer which selectively permits gas flow from the second opening of the second layer through the second channel and out of the device; and,
an amount of flowable liquid deposited in the first channel between the first and second openings.
