9min @thecrashcourse clip - the Mighty Power of #Nanomaterials: Crash Course Engineering #23

Text from youtube "Just how small are nanomaterials? And what can we do with stuff that small? Today we’ll discuss some special properties of nanomaterials, how some can change at different sizes, and the difference between engineered nanomaterials and ones that occur naturally. We’ll also talk about some of the future research that’s needed on the use of nanomaterials."
