Geology!

Why my geology class is awesome.
Aside from the fact that Brother Skinner is LITERALLY THE BEST PROFESSOR ON CAMPUS {joke times during class, every slideshow is guaranteed to have several pictures of irrelevant dinosaurs, and he's the most often quoted professor on Overheard@BYU}, the subject is really amazing. It's not just the study of rocks folks, it's the stuff your wildest dreams are made of. If, that is, you dream about volcanoes and plate tectonics. Whatevs. Today, in our lesson about the different kinds of volcanic eruptions he took us outside and we did the famous Diet Coke-Mentos experiment.

A volcano.
The magma pushing through the lithosphere creates pressure.

If the magma has the right composition, temperature, and pressure it will explode!
Like Mount St. Helens. :)

Any professor that uses an excuse to do crap like this is awesome.
