How does a Thermos keeps drink warm?

Thermos are double walled containers. Between each wall, the space is vaccuum sealed, so there are no air particles. This decreases the transfer of energy (by convection) from inside the warm drink to outside in the atmosphere. The second way your thermos keeps your drink warm is the shiny surface inside your thermos. Photons carrying energy bounce off the shiny surface inside the thermos, keeping high energy photons around the infrared wavelength inside the thermos. Next time you drink from your thermos, think science!
