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!

Fun to Play in the Dark
I was intrigued by the black-paper notebooks and suggested metallic pens. As an artist, I've always loved the way things look on black paper, and I thought it was a great idea to have a whole notebook full to sketch pictures and take notes. It makes me happy just to open the pages and play.
