>Air doesn't insulate... It has to be a vacuum for it to be an insulator, not just and old void between the outside and the drink.
What? That's just plain wrong.
Still air is a tremendous insulator. Not as good as vacuum, but it's still pretty darned good.
Pink fibreglass is mostly just a really good way to hold air in place as an insulator. The fiberglass (or the foam, or whatever) just keeps convection from transferring what little heat there is.
These kinds of cups have an air space between the inner and outer wall, and it's just air, not vacuum (plugged by a silicone plug in the bottom of the cup) and it works beautifully.
