Keep those neurons firing with 18 ounces of coffee – piping hot and ready for you even if your shift keeps you running around the department all morning. Or you could let yourself get lost in the textural gyri and sulci wending their way around this Brain & Neuroscience Flask while you re-hydrate. 

With a textured design for a unique tactile experience, this vacuum-insulated 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!

Love!

I purchased 3 of the same type of water bottle, one for me, and my two professors. I love it, they both love it, and we all agree that the detail is amazing. The only reason I gave 4 stars instead of 5 is because I wish the water bottle was bigger for how much it cost. It’s a tad on the smaller side. But it’s okay, I still love it!

wow

The brain anatomy flask is STUNNING. The flask is lovely, it keeps my water ice cold for 8+ hours. The diagrams are extremely detailed, and they are slightly raised. the details are slightly shiny. The pictures on the CS website are great, but the detail is just so meticulous on this flask, the print is raised a little, which gives an interesting tactile experience, and it is very shiny making the arteries and veins stand out. if you have a neurology buff this would make the best gift ever, i would lose my mind if I received it. Will be gifting this in the future.
