'Insect' 500mL Vacuum Flask

$79.00

Whether you'll be spending your day hunting for exotic butterflies or cataloguing endless specimens of dung beetles, this Insect Vacuum Flask has got you covered. Fill it with a fancy chai, your favourite cold brew, (or hey, something stronger, we're not judging) and your drink will be waiting for you at just the right temperature whenever you're ready.

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!

High-grade stainless steel + BPA-Free plastic threads (threads do not touch the drink)

Holds 500ml
