Why does a hot potato stay hot when wrapped in aluminum foil?

A hot potato wrapped in aluminum foil stays hot because the foil reflects radiant heat back to the potato, while also trapping steam and preventing hot air from escaping via convection, effectively creating an insulating barrier despite aluminum's high conductivity. While aluminum conducts heat well (which helps it cook faster initially), its shiny surface reflects heat radiation, and the tight seal blocks air movement, both crucial for retaining warmth.

Why does food remain hot in aluminium foil?

Aluminium foil keeps things warm primarily by reducing heat loss through radiation and, to a lesser extent, by limiting convective and conductive losses when used as a barrier.

Why should you be putting aluminum foil behind your router?

Aluminum foil acts as a barrier, bouncing the signal away from itself and toward open areas. By placing it behind the router, you can focus more of the signal in a desired direction — for example, away from walls and toward rooms where you actually need a stronger connection.
