How do thermoses keep coffee hot?

Melissa and Jam, Bleav
About this episode

#033 Rebroadcast

That's right, we are sort of talking about coffee this week. Or rather, how to keep it hot. Nowadays we all have some version of a thermos for our coffee, tea, water, or what-have-you. Today Melissa and Jam try to get to the bottom of how those work. How do they keep things hot and cold? What's between the two layers (or whatever) and how is it so good at insulating? Is it a vacuum? Can someone please tell me what the heck is going on?
