1. A method for transporting gas out of bubbles of a foam and/or bubbles of a bubble-containing liquid, comprising:
at least partially submerging a conduit comprising an external surface into the foam and/or the bubble-containing liquid, wherein:
the conduit comprises a porous wall portion, the porous wall portion comprising at least one submerged pore establishing a gaseous pathway from the external surface of the conduit, through the porous wall portion of the conduit, and to an internal gas passageway of the conduit,
the at least one submerged pore is configured to restrict the transport of a liquid of the foam and/or the bubble-containing liquid through the wall portion, and
the external surface of the conduit breaks liquid/gas interfaces of the bubbles of the foam and/or the bubbles of the bubble-containing liquid such that gas from within the bubbles of the foam and/or the bubbles of the bubble-containing liquid is transported from the bubbles, through the gaseous pathway, and into an interior of the conduit.
