Awesome invention

The video

Today, I saw a video on TED that showed an invention that saves lives before anything goes wrong. It's a simple sleeping bag made for babies that have gone through a premature births. It can unfold both on the sides, and on the bottom as well. What really makes it unique Is that it has a wax-like substance that melts at the human body temperature. Because of that, it is able to keep the baby warmer for the cheap price of $25. Now that's a huge difference from the classic incubator, which is much harder to sterilyze and even more expensive. I know that a lot of guys my age would say "so what? Do we really need it?". We don't need it as much in america, which is why it is being released first in India. That is where a mother of a premature baby that died met one of the creators of the invention, which I can tell really meant a lot to the creator of this awesome invention.
