A practical guide to freezing your boss’ hat in a block of ice [Photos]

Working professionals are looking for innovative ways to stay cool during the sweltering Japanese summer, and now one method involves freezing a boss's hat in a block of ice. After deciding to freeze the hat of SoraNews24 owner and founder Yoshio, we needed to determine the steps required to execute this unusual cooling technique.

To begin, we placed Yoshio's hat upside-down in a large container, like a cooking pot, and stuffed a plastic bag inside the hat. The next step involved filling the container with water and placing it in the freezer. We left the frozen hat to sit for three days before taking it out and finding that it had frozen into a solid block resembling a curling stone. The hat's appearance was striking, with the solid black fabric contrasting the textured ice.

However, before the ice hat could be worn, we had to address its structural issues. We filled the plastic bag inside the hat with warm water, carefully pouring it over the frozen surface to melt the ice around the bag while preserving the rest of the hat's shape. This process altered the hat's center of gravity, making it necessary to grind off excess ice using a straight file to ensure a secure fit on the wearer's head.
