Here's how it works: the space between the inner and outer flask wall is evacuated, creating a vacuum (well, a partial vacuum anyway...). In order for heat transfer to take place from the outside world into your cold drink, or from your hot drink to the outside world, it needs nearby molecules to excite. If there aren't many molecules nearby, as is the case in a vacuum, the heat's energy can't easily be passed along, so your drink stays close to the temperature it was when you put it into the flask for a really long time. 

Simply stated, vacuums make great thermal insulation!

DNA Flask as a gift

My scientist friend was ecstatic when she opened my surprise gift! I am telling my friends about Cognitive Surplus around the holidays to see if they take the hint and buy something for me.

Genetics & DNA Stainless Steel Vacuum Flask

It's awesome–way better in person than the photo's give credit for. Raised texture for a tactile experience and not just a cheap flat graphic. Really happy with this.

love love love this water bottle ... It's a bit smaller than i had expected but that's more on me for not checking the dimensions than the bottle itself
