That's so cool! I never seen that before :p
That 3rd picture looks like a god punched a hole in the ground lol. The earth is amazing in so many ways, love the videos! Now I have to go see what makes the water explode like that. I know pressure but, why?
Something something thermal energy plate movement thingy. I forget :S. Probably will go google that picture again with the demo haha. It is certainly very interesting!
