Claim:
1. A spray foam dispensing apparatus comprising: a container within which pressurized chemicals reside used to synthesize a polyurethane foam or a polyurethane froth, said container further comprising at least one pressurizing dispensing propellant; and a dispensing conduit selected from the group consisting of and further wherein the at least one thermochromic material in either the plastic dispensing straw or the plastic portion of the metallic nozzle changes color by determining the temperature of either a high volume flow of pressurized chemicals or a high volume flow of a synthesized froth foam or both egressing through the plastic dispensing straw or the plastic portion of the dispensing conduit to illustrate to an end-user of the foam dispensing apparatus if the pressurized chemicals and the at least one pressurizing dispensing propellant used to prepare the polyurethane foam or the polyurethane froth are at a minimum temperature for proper chemical cure and wherein the at least one pressurizing dispensing propellant changes to a gaseous state component during travel through either the plastic dispensing straw or the plastic portion of the dispensing conduit and egress therefrom into the environment with turbulent flow between the pressurized chemicals and at least one pressurizing dispensing propellant.
