The complete guide to making hot ice and sodium acetate. How to create it, fix it, and use it. All methods from baking soda and vinegar to laboratory synthesis are shown.
The basis for hot ice is sodium acetate trihydrate, which is heated above its melting point and then cooled below its melting point so it's supercooled. It's still liquid and quickly solidifies when a seed crystal is introduced.
Sodium acetate trihydrate can be bought, or made at home by mixing three tablespoons of baking soda with one liter of vinegar and boiling down.
The video shows a detailed step by step instruction on how to do this as well as how to fix problems you might have.
