1. A system for making one or more degradable drinking straws, the system comprising:
a base plate configured to form one side of a reservoir for holding a liquid to be frozen into the one or more degradable drinking straws;
one or more tubes configured to contact the base plate and positioned within the reservoir and to contact the liquid to be frozen, wherein a content of the one or more tubes consists of a first fluid and a second fluid;
at least one connecting bar in fluid communication with the interior of the one or more tubes, wherein the at least one connecting bar and the base plate are substantially parallel and separated by the reservoir;
at least one source of the first fluid, the first fluid at a temperature at or below the freezing point of the liquid to be frozen into the one or more degradable drinking straws, in fluid communication with the at least one connecting bar configured to feed the first fluid into the at least one connecting bar and therefore into the one or more tubes; and
at least one source of the second fluid, the second fluid at a temperature at or above the melting point of the one or more degradable drinking straws, in fluid communication with the at least one connecting bar configured to feed the second fluid into the at least one connecting bar and therefore into the one or more tubes.
