How to make hot ice

All you need are two common kitchen ingredients to make hot ice - a non-toxic chemical that crystallizes when you touch it into a material that looks like ice except it gives off heat. See how to make hot ice and get ideas for fun hot ice activities.

You Will Need :

• White Vinegar
• Backing Soda

Process :

          Mix one liter of vinegar with 4 tablespoons of baking soda. These chemicals react to form nontoxic sodium acetate or hot ice in water. You need to boil off most of the water, so heat the solution until it is boiling and keep applying low heat until you see a crystal skin start to form on the surface of the liquid. Remove the hot ice solution from heat, pour it into a new container and refrigerate the solution until it is chilled.

          When the hot ice has cooled, you can get it to instantly crystallize simply by touching it. You can try crystallizing the hot ice as you pour it, too. Either way, the solution will give off heat as it crystallizes.

          You can re-dissolve and reheat the hot ice to play with it again or you can throw it away when you are finished. 

          I hope you've enjoyed making hot ice.
