I'm not sure if a Dark Field Microscope will let you see water crystals. They some how flash-freeze the water than look at them. I haven't figured out how to do that yet. But let me know how it works out. That is a very interesting subject to me too.
I believe that everything can be scientifically explained. Everything has its own laws but I believe that GOD made everything, and everything is in harmony. As far as us (humans) trying to understand everything, well, I guess we can only try.
I have bought a movie called " Water the great mystery" and its awesome. In it they have scientists from all over the world explaining their understanding of water and how they think it works. They get deep into it. I suggest you get your hands on that DVD.
