Snake Eats Crocodile [PICS]

This is what is trending now and I am all about it! I have a morbid fascination with things like this. A snake eating a crocodile, how gross and cool at the same time. lol 

My first question was, how? Seriously, just how? Leo had to explain to me how snakes can actually eat humans. I had no clue. Can someone explain the process of digestion to me please? lol If you haven't seen the video that everyone is talking about, MUST WATCH HERE:
