This hot ice experiment may look cool, but it’s hot to the touch! Learn all about the science behind hot ice below What you need: 4 cups of vinegar 4 TBSP baking soda Medium pot Liquid measuring cup Plate How to make hot ice: Pour 4 cups of vinegar into a medium pot and slowly add 4 tablespoons of baking soda to create a sodium acetate solution. When the solution starts to fizz, keep stirring until it stops producing bubbles and all of the baking soda has dissolved. Boil the solution over medium-low heat until you can see crystals on the side of the pot. Then, pour the concentrated solution into a liquid measuring cup and let it sit in the fridge to cool. Scrape some of the solid sodium acetate off the bottom of the pot and put it on a plate. Slowly pour the solution on top of the solid, and watch crystals form! What’s going on? When you create, boil down, and cool the solution, you’ve dissolved way more sodium acetate than you could mix into the same amount of cold water. In oth...
