1. A mixing system configured to mix a solution comprising a liquid adhesive and a gas, the mixing system comprising:
a manifold configured to receive the solution, a mixing chamber in fluid communication disposed in the manifold, and an output in fluid communication with the mixing chamber and configured to output the solution;
a rotor configured to rotate within the mixing chamber so as to mix the solution, wherein the rotor and the manifold are configured such that a shear rate between the rotor and the manifold is greater than 100 reciprocal seconds when the rotor rotates at less than 100 revolutions per minute (RPM); and
a motor configured to rotate the rotor at less than 100 RPM such that the rotor mixes the solution at the shear rate of greater than 100 reciprocal seconds.
