Thermodynamics challenged

Well, only the
Third Law, not the whole theory - not yet.

The third law states that, as materials approach to absolute zero temperature, their enthropy also approaches zero.

But which is the maybe most fascinating, yet common, material of all: water, has been shown to break this rule. It is not the only one: other non-crystaline materials also breach the same "law". And now artificially generated meta-materials that mimic the behaviour of water ice have been shown to do exactly the same. The third law of thermodynamics seems therefore to be more like a guideline, not any absolute law.
