Not bad
I was thinking that this was just going to be a single loop that was more like a joke flash, but I was pleasantly surprised. As I know some stuff about science, I could understand where you were going. I think my favorite part was when the flames turned Walter into steam and he sort of rose up like a ghost. It was pretty innovative, especially when he turned into bird poop. My complaint is that it does look like the animation used in this is a bit too simple. You put in a great choice of music too.
