How does memory foam pillow work?
Question : How does memory foam pillow work?
I heard that memory foam pillow are made from technologies that came from space. I am interested in understanding how the pillow has a memory and what are the materials used to create this memory foam pillow. It is also interesting to understand the kind of transition needed to take a space age technology into a commercial product such as a memory foam pillow.

lol. Well, the technology comes from NASA, which is based on Earth. 
I believe the real memory foam from NASA is not-quite-closed-cell foam. (you’ve heard of closed-cell foam pads right? Foam containing closed air-bubbles, so that the pad will not soak up moisture) And it just takes the air a long time to reenter the bubbles (since they only have a very small opening to let air in) once you squish it out. It is also a dense but very pliable material. These are the things that help it hold its shape for a little while after you compress it.
To see how NASA technology becomes commercial, go here and click on “How does NASA transfer its technology to the private sector?”: http://www.sti.nasa.gov/tto/spinfaq.htm#spinfaq5
oooooohhh… Pillows From Space !!!
Total BS
First of all, you don’t need fancy pillows in space. There’s no gravity to weigh you down so you don’t need something soft to rest your head on. Instead of something below you to hold you up, you need a light bungee cord above you to keep you from floating away. So forget about this wooshy space technology. It’s a crock.
So’s the “memory” bizness. Heck, it’s just a hunk of foam that doesn’t bounce back very quickly.
And what’s the deal with the wine glass that doesn’t tip over? If my wife is bouncing on the bed when I’m asleep I’d rather know about it than not.
In general anything that’s heavily advertised is crap. GM spent $ 600 million advertising the J cars, they were pure crap. Anything that’s any good needs no advertising. You don’t see ads “Eat food, it’s yummy!”. I have yet to see an infomercial for a product that is a good value.
