Birds 950 mL Steel Bottle
Perfect for long days of bird watching or patient vigils waiting for a glimpse of an elusive specimen, this big 32 oz Birds Steel Bottle will have your drink at just the right temperature whenever you're ready for it. Particularly if you're the type to get lost in your work for hours, it's nice to know that your drink won't have gone tepid while you were having a moment of genius.
With a textured design for a unique tactile experience, this flask will keep your drink hot or cold until you're ready to enjoy it.
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!
