In 1952 NBC launched a network radio program featuring Howdy, and in 1954 Howdy Doody became an international television hit with a Cuban and a Canadian show, using duplicate puppets and local talent, including Robert Goulet as Canadian host, Timber Tom.

You're right that IF the metal calorimeter and the styrofoam calorimeter were both perfect and behaved in the way that we usually pretend calorimeters do (they don't absorb or lose heat) then they should produce identical results, for the enthalpy reason you provide.
Glass is far inferior to paper, plastic and Styrofoam in terms of insulation. Thermal conductivity in terms of BTU/(feet - hour - degrees F) is 1.82 for glass, 0.09 for paper, 0.06 for Styrofoam. The conductivity of plastics varies depending on the materials: for polypropylene and polycarbonate, the thermal conductivity values are 0.69 and 0.35, respectively.
