WebA Vacuum. A thermos is a flask with a double-walled container inside it. Air is removed from the space in-between the walls. Now heat can't escape from the soup; it's surrounded by a vacuum. And ... Flasks also work for cold drinks. If heat can't escape from a vacuum flask, it follows that heat can't penetrate into a flask from outside either. The sealed stopper stops heat getting in by convection; the vacuum stops conduction, and the metal lining between the outer case and the inner chamber stops heat … See more Thermos® Vacuum Insulation Technology: A short (37-second!) video explaining the basic principle of a Thermos flask.
