It crystalizes instantly when you pour it, allowing you to create a tower of crystals. Since the process of crystallization is exothermic, the “ice” that forms will be hot to the touch. Science is so cool!

Why is hot ice called Hot Ice?

“Hot ice” refers to a popular chemical demonstration in which a solution of sodium acetate dissolved in water and placed in a freezer instantly solidifies when poured from its container or when a single crystal of solid sodium acetate is dropped into the solution.

What do you think is the science behind hot ice?

The Science Behind Hot Ice

That means the sodium acetate is in liquid form below its usual melting point. ... The crystallizing sodium acetate releases energy in the form of heat and is an example of an exothermic process. Sodium acetate is often used in hand warmers as it release heat when crystallizing!
