Botanical Pharmacy 18 oz Steel Bottle
Keep your herbal tea or fancy chai latte hot for hours so you can enjoy it all throughout a long shift. This Botanical Pharmacy flask will happily keep your favorite drinks hot or cold so you can enjoy them on your own time.
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!

United StatesAbsolutely stunning!
I so love this water bottle! I bought it for my brother's graduation and he has been using it nonstop. The artwork on it is perfect, and the only reason it received 4 starts instead of 5 is because the lid and metal hook is not as sturdy as I would have liked. It also takes a few tries to screw it on correctly. However, it is still absolutely worth the purchase!
