## Unscramble the Blue Letters

So what are nanoparticles, and what does it really mean to be nano-sized? Well, there are many different types of nanoparticles made out of various materials, such as metal-based nanoparticles or fat-based ntoaaerlnpics. But to really illustrate what it means to be nano-sized, I took one of my hair strands and placed it under the moiorccpse. Now, I have very thin hair, so my hair is approximately 40,000 nanometers in diameter. So this means, if we take 400 of our nanoparticles and we stack them on top of each other, we get the thickness of a single hair sartnd.
