A DROP of WATER

• These water molecules are displayed as "Stick" figures.
  

  You can see how much space they actually take up by clicking on the MDL logo in the middle of the screen. Then click on "DISPLAY" and "SPACEFILL... vanderWaals radii".
  

  This is a "Spacefill" model.
  

Question:

Can you find any patterns to the way these WATER molecules contact each other?

Question:

It is well known that ice floats, can you now explain why?
