Water: the strangest substance in the Universe

In this live recording from Science Stories' Salon #5, Professor Søren Keiding from the University of Aarhus talks about the many strange properties of water (in Danish). Water has been called by scientists the strangest substance in the universe, and water behaves in many ways differently than any other substance we know. Water is the only substance that expands in its solid form and floats on top when it freezes to ice. It's just one of the approximately 45 strange properties that only water has. 

This salon will also provide answers to: Where does our water come from here on earth? Why is water and life always connected? What makes water special? What can water and why is it so suitable as a "host" for biology? What can a water molecule and what can two? Can water remember? What is Heavy Water? Do we understand water? And much more.

About halfway through the program, Søren Keiding and Jens Degett illustrate the location, vibration and rotation of atoms in connected water molecules by acting as atoms with bodies, arms and hands. This can be heard but not seen in this podcast.
