Professor Pinkin: Geology Lab #1
Transcript:
Today we will discuss Mohs' scale of mineral hardness.
#1 Talc is the softest: #10 diamond the hardest. Gypsum can scratch #1. Calcite can scratch #1 and #2, and so on.
As you run your expiriments, please don't lose the diamond each of you has. I have to return them to the jeweler.
Professor, Shouldn't a hammer be at number 11?
What? Why?
My diamond smashed when I hit it with a hammer.
Yeah, mine too!
You're right. So if hammers are harder...
...maybe guys should give their girls hammers instead of diamonds.
