Bizarre fourth state of water discovered
Bizarre fourth state of water discovered Scientists at the Oak Ridge National Lab (ORNL) have discovered that when (water) put under extreme pressure in small spaces, the life-giving liquid can exhibit a strange fourth state known as "tunneling". Quantum tunneling means that a particle, or in this case a molecule, can overcome a barrier and be on both sides of it at once – or anywhere in between. Think of rolling a ball down one side of a hill and up another.
