I wonder if actual tin foil would behave differently from the aluminum foil that we are all now using.
"The thermal conductivity of aluminum is 237 W/mK, and that of tin is only 66.6 W/mK, so the thermal conductivity of aluminum foil is much better than that of tin foil. Due to its high thermal conductivity, aluminum foil is often used in cooking, for example, to wrap food to promote even heating and grilling, and to make heat sinks to facilitate rapid heat conduction and cooling."
The things that you can't measure are... not.
You're not weaponizing Gell-Mann amnesia against us are you?
Kudos
