Whether you’re studying nocturnal animals or just enjoy a good walk in the trees, fill this bottle with your favorite brew and let your thoughts drift into the woods. Sip and enjoy the way the sounds of the forest change as twilight falls. Don’t worry, there’s no rush. Your drink will stay at just the right temperature for hours.
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 the vacuum flask 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!
