  1. First of all your blog has a new look, which I like. Next how is this trick happening? I am sure the water is not actually turning into ice so easily, but what is happening?

  2. This water is already cooled below the freezing point. Only nucleation is needed for solidification to start, the water then freezes quickly. In some of the videos you can see the interface move through the water.
