Make Hot Ice Using Vinegar and Baking Soda

You can supercool sodium acetate and cause it to crystallize on command.
You can supercool hot ice or sodium acetate so that it will remain a liquid below its melting point. You can trigger crystallization on command, forming sculptures as the liquid solidifies. The reaction is exothermic so heat is generated by the hot ice. Anne Helmenstine

You can make 'hot ice' or sodium acetate at home using baking soda and vinegar and then cause it to instantly crystallize from a liquid in 'ice'. The reaction generates heat, so the ice is hot. It happens so quickly, you can form crystal towers as you pour the liquid into a dish.

Experiment Materials: vinegar, baking soda

Make Hot Ice
