Heartbeat 32 oz Steel Bottle
Study your cardiac rhythms while keeping hydrated! Nicer looking than an EKG pocket guide, this Heartbeat Flask is both functional and aesthetic. Nicer looking than an EKG pocket guide, this heartbeat travel bottle is both functional and aesthetic. Fill it with ice cold water and take it to the gym for your cardio workout, or top it off with herbal tea for a long night shift in the cardiac ward.
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!
