Modern science has revealed what people all around the world have known for centuries – tea is amazing! In addition to keeping your earl gray piping hot or your iced chai cool and refreshing, this double-walled flask celebrates the complex array of molecules that give tea its unique qualities and flavors. Molecules such as theaflavin, which adds bitterness to black tea – or L-theanine, which alters your brain waves to promote relaxation.

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!

Awesome thermos but a mistake in a chemical structure

I love the thermos it works well, keeps things hot or cold and doesn’t leak. I have discovered an error in the structure of theaflavin, OH shouldn’t have a double bond, the oxygen below it should have the double bond. For that chemistry mistake I removed a star, hopefully this is corrected soon.
