Description

Great spaceship designs (Engineering Wonders of the 21st Century)"Launching a spaceship, monitoring it in orbit, and bringing it back down to Earth and doing it all while keeping the crew safe is a huge undertaking. Engineers and physicists have to carefully design each component. For example, a space shuttle has a blunt nose because this helps keep the worst of the heat of atmospheric reentry away from the body of the shuttle. This volume examines the science behind the design choices of rockets, shuttles, space

Interesting pillowcase that does run cool to the touch
To begin: I'm a 64 y/o woman who still gets hot flashes, despite air-conditioning and a fan blowing on me at night. It's the sheets off then blankets on routine that so many of us know. I ordered this pillowcase hoping that I would find some kind of relief in the night, even it was only for my head. The fabric is very unusual. It's a silky nylon blend, very swishy and soft. It reminds me of luxury, expensive women's lingerie. It's extremely slippery, moreso when you have your head on it; there certainly won't be any resistance or pulling on the hair all night. I washed it before using it, put it in a mesh bag to protect it from getting snagged. It washed and dried as good as new. One thing to note: because it is so slippery the pillow may want to slide a little out of the pillowcase. I slept quite well and did not experience any heat or sweating on it. The reason for the 4* and not 5* is the price, at almost $20 it is a bit pricey for a rectangle of nylon fabric. I could see if it were real silk, but it's not. Otherwise it's exactly what it purports to be.

The perfect cooling pillows!!
Photo taken after about half of the filling was removed and many months of use. Still my favorite pillows ever! I absolutely love these adjustable cooling pillows! They keep me cool all night long (must use without a pillowcase for cooling effect.) They arrived with enough filling to make them super firm and extremely thick. They took several hours to fully puff up. I removed about half the filling to make a more plush pillow which I prefer and they’re still thick and comfy. They offer the perfect amount of support. I’m actually sleeping better! Bonus: I saved the extra filling and used it to stuff throw pillow covers.

I did have to take some stuffing out for my comfort. After that it is amazing! Love that the pillow is cool!
