Through the centuries, humans have always had a relationship with water. As we evolved, we learned to fish along the shores, create canals for farming, and build boats to sail down rivers and across the seas. But the most vital relationship is the one we have with water. So stay hydrated with a bottle that is more than cool, but it keeps your water cool too!

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!

Happy customer
I’ve been looking for a journal with this layout for quite some time. It’s exactly what I wanted and it arrived quickly
I ordered several different wrapping paper sheets, and am super pleased with all of them. The quality is outstanding!

super cute
Mouse pad is a great size and wonderful design
I ordered two of the mouse pads, one for myself to use at work and one to use at home. The designs are great and the quality of the graphics seems excellent.

Best planner
I love these planners, there is enough room to record everything I need for a day, and still see the week view. The month pages allow simple forward planning They are small enough to easily fit in a purse or backpack, perfect!

Always a hit
I’m not a scientist, but I’ve won mother-in-law-of-the-year prize more than once with my CS gifts to my cancer researcher DIL, who is always delighted with her presents. It was hard to top the electrophoresis mug, but the DNA towels might do the trick!

great big mug
why is it so hard to find a mug large enough to fill with tomato soup anddunk a grilled cheese sandwich in? Or make a double tea bag cup of tea to last you throughout the morning? This is what I'm talking about baby! It's a big 'un. And sturdy. And nerdy.

First and Forever Favorite Washi
It's gorgeous. I like darker, less cutesy washi, and this was the one that got me hooked. I came back to get another roll.
