Back in 1964, our nations finest minds at NASA developed a material that would eventually end up in everyone's first aid kit: The Space Blanket. The space blanket is made of a lightweight piece of plastic that is usually coated with a very thin layer of aluminum. Once you're snuggled inside the space blanket, Presto! You are enveloped in a radiant barrier that is reflecting back 97% of your own radiant heat. Imagine being on an needing an emergency radiant barrier on an Adirondack mountain hiking trip.... The space blanket proabably saved that guy's life.
