Women of Science 18 oz Steel Bottle
Here's a travel flask dedicated to some amazing ladies who helped change the course of scientific history. Let them inspire your next breakthrough while you enjoy your hot coffee, ice water, or cold brew at your own pace. Hats off to the Great Women of Science – past, present, and future.
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!
