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.

Hand-wash only

Compostable Packaging

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!

So Much Better than I anticipated

This bottle is very high quality. It keeps warm things warm and cold things cold for hours. Almost a little too well, I had hot coffee in it and I burned my mouth! The print quality is exceptional and it’s raised which is fun. I get tons of compliments on it everywhere I go.

Unique and Functional Flask

This item is one of those things you think you might not need, but one look at it and it grabs your attention immediately. As a psychology major, I knew the universe was trying to give me something cool. I bought this along with a 5-pack set of engineering notebooks for my boyfriend, and some fungi/forest animal stickers as well. This flask is so smooth, the brain scans were given so much attention to detail and my water stays cool no matter the temp.
