In the 9th grade, we were subjected every so often to geology videos featuring bearded, bespectacled geologists. Recently I was reminded of them while looking at some cool rings made of raw cut minerals/rocks/gems. Needing vaguely interesting things to watch while making hundreds of houses for my mobiles, I went on a search across the interwebz.
And found THE VERY videos I remember watching. I drew a picture of the main narrator and everything, back in the day.
Here is the link, in case anyone cares to take a look.
Now, back to folding and gluing!!
