Infuser Basket for Stainless Steel Bottles
Turn your flask into a tea infuser with this stainless steel infuser basket! These are sized to fit the infuser-compatible bottles. They slide in easily and snap into place so you can infuse on the go. For spa water or other infusions, the top part of the basket can be used without the bottom, leaving you more space in your drink.
Please note that not all of the flasks are infuser-basket compatible, so make sure you double check the listing for the infuser symbol!
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!
