We all know we need science for a lot of important things, but watching these people build this piece by piece really made me think: sometimes all it takes to solve deadly problems is very simple solutions. Like, really simple.
*NOTE* I do know that this is still technically science, of course. I was merely trying to emphasize the simplicity of it and how it didn't take years of research/engineering/tests to do this. I love science. Science is real. End.
