How to make Hot Ice at home – Amazing Science Experiment

Sodium acetate or hot ice is an amazing chemical you can prepare yourself from vinegar and baking soda. You can cool a solution of sodium acetate below its melting point and then cause the liquid to crystallize. The crystallization is an exothermic process, so the resulting ice is hot. Solidification occurs so quickly you can form sculptures as you pour the hot ice.

Here is the reaction between the baking soda and vinegar to produce the sodium acetate:

Na+[HCO3]– + CH3–COOH → CH3–COO– Na+ + H2O + CO2

  1. The video is a bit confusing as it says salt in the first part and then soda when they are putting it in the pan. It helped to come to the actual web page as it has written instructions. Also do you have to put some of the dry contents of the pot on the objects in order for the reaction to happen?

  2. did you use a specific type of vinegar? I noticed in the vinegar clip, the caption shows 80%. is that 80% concentration of something else?
