The trick is slow freezing to allow air to escape in one direction.[0] This means insulating the container so that it freezes slower in all but one direction. Note that water gives off heat when it phase changes from liquid to solid. It's visible under FLIR when pouring supercooled water onto a nucleation point. 0. https://www.youtube.com/shorts/odhf1d7RBL4 |
