Instructions for How to Make "Hot Ice" With Sodium Acetate.
This 500g bottle of Sodium Acetate will produce approximately TEN OUNCES of supersaturated solution.
When sodium acetate trihydrate crystals are heated, they melt. When this melt cools, it gives a supersaturated solution of sodium acetate in water. By clicking the solution, a nucleation center is formed which causes the solution to crystallize into solid sodium acetate trihydrate again. (ref wikipedia)
