Hardness Comparison

In this video, we do more than scratch the surface of what the hardest materials on Earth are. We compare everything from the softest to the hardest materials and everything in between to see which materials are insubstantial and which materials are impenetrable.

Note: The Scale used to measure hardness in this video is the Mohs hardness Scale.
