Why do flasks explode?

We suspect a crack or leak in the flask caused the explosion. When a flask partly open to the atmosphere is immersed in liquid nitrogen, air is condensed. When the flask is removed from the liquid nitrogen, the pressure can build quickly due to the phase change from liquid to gas causing the glass to shatter.

Why does my thermos not stay hot?

Thermos flasks work in two main ways. They insulate by using a vaccum between a double-walled glass vessel and the walls of this vessel also reflect heat as they are silvered. If your flask isn’t visibly damaged (look underneath the plastic cover) then a small crack or defect may have caused the vacuum to fail.
